Description

本発明は、比較的高所の天井等に装備される直管型蛍光灯の着脱交換器具に関するものである。   The present invention relates to an attachment / detachment / exchange device for a straight tube fluorescent lamp mounted on a relatively high ceiling or the like.

直管型の蛍光灯は、図２０で示すように直線状のガラス管Ｇと、ガラス管Ｇの左右に取り付けられた口金Ｃ１，Ｃ２と、口金Ｃ１，Ｃ２より突出する口金ピンＰ１，Ｐ２とを備えて構成されている。この蛍光灯の取付け設備としては、ソケットケースＮ１，Ｎ２を反射カバーＲの左右内側に備え、ソケットケースＮ１，Ｎ２でバネ変位可能に収容したソケットＳ１，Ｓ２に口金Ｃ１，Ｃ２を当接し、口金ピンＰ１，Ｐ２をソケットＳ１，Ｓ２の端子穴（符号なし）に差し込むことから電気的に接続するものがある。 As shown in FIG. 20, the straight tube fluorescent lamp includes a straight glass tube G, caps C 1 and C 2 attached to the left and right of the glass tube G, and a cap pin protruding from the caps C 1 and C 2. It is constituted by a P 1, P 2. As a mounting facility for this fluorescent lamp, socket cases N 1 and N 2 are provided on the left and right inner sides of the reflection cover R, and the caps C 1 are inserted into sockets S 1 and S 2 which are accommodated in the socket cases N 1 and N 2 so as to be spring-displaceable. , C 2 are brought into contact with each other, and the base pins P 1 , P 2 are inserted into the terminal holes (not shown) of the sockets S 1 , S 2 so as to be electrically connected.

その蛍光灯の場合、取外し時には一方のソケットを灯全体で押すことによりソケットケースの内部に没入させると共に、他方の口金（「口金ピン」含む。以下同じ）を相対する他方のソケット（「端子穴」を含む。以下同じ）より外し出し、また、取付け時には一方のソケットを灯全体で押すことによりソケットケースの内部に没入させると共に、他方の口金を相対するソケットと合わせて取り付ける手順で着脱交換することが行われている。   In the case of the fluorescent lamp, when removing it, the socket is pushed into the socket case by pushing the entire lamp, and the other base (including the “base pin”, hereinafter the same) is opposed to the other socket (“terminal hole”). The same applies to the following). When installing, press one socket with the entire lamp to immerse it inside the socket case, and replace the attachment and detachment according to the procedure for attaching the other base together with the opposite socket. Things have been done.

天井等の比較的高所に装備される蛍光灯の着脱交換に対応するべく、従来、高所にまで伸ばせる長尺な取手用ポールを備え、蛍光灯のガラス管を把持乃至は解放可能なチャックを取手用ポールの上端側に取付固定すると共に、蛍光灯の口金を銜えて灯全体を軸線方向に横ずらし可能な可動爪をチャックより離れた取手用ポールの横方向に備える直管型蛍光灯の着脱交換器具が知られている（特許文献１，２）。   A chuck that has been equipped with a long handle pole that can be extended to a high place and that can hold or release the glass tube of the fluorescent lamp, so that it can be attached to and removed from a relatively high place such as a ceiling. A straight tube type fluorescent lamp that is mounted and fixed to the upper end of the handle pole, and has a movable claw that can be displaced laterally in the axial direction by holding the base of the fluorescent lamp in the lateral direction of the handle pole away from the chuck There are known attachment / detachment / exchange devices (Patent Documents 1 and 2).

上述した可動爪に代えて、口金とソケットとの隙間に差し込んで灯全体を軸線方向に横ずらしするよう口金の端部面より押圧可能な係合片を取手用ポールの上端側に備え付けた直管型蛍光灯の着脱交換器具も知られている（特許文献３，４）。   Instead of the above-mentioned movable claw, it is a straight line provided with an engaging piece that can be pressed from the end face of the base so as to be inserted in the gap between the base and the socket and horizontally shift the entire lamp in the axial direction. A tube-type fluorescent lamp attachment / detachment exchange device is also known (Patent Documents 3 and 4).

その直管型蛍光灯の着脱交換器具は、蛍光灯の取外し時で説明すると、いずれも、蛍光灯のガラス管をチャックで把持すると共に、灯全体を可動爪または係合片でチャック側に向けて押し送りする。換言すると、ガラス管のチャックによる把持（固定点）に対し、灯全体を可動爪または係合片の可動側で押し送りするものとして構成されている。   In the case of removing and replacing the fluorescent tube, the straight tube type fluorescent lamp attaching / detaching apparatus is such that the glass tube of the fluorescent lamp is gripped with a chuck and the entire lamp is directed to the chuck side with a movable claw or an engaging piece. To push. In other words, the entire lamp is pushed by the movable claw or the movable side of the engaging piece with respect to the grip (fixed point) of the glass tube by the chuck.

それによると、灯全体を可動爪または係合片で押し送りするに伴って、可動爪または係合片の押圧による過度なストレスがチャックとの間でガラス管に加わるおそれがある。   According to this, as the entire lamp is pushed and fed by the movable claw or the engaging piece, excessive stress due to the pressing of the movable claw or the engaging piece may be applied to the glass tube between the chuck.

上述した以外に、略台形に折り曲げた板バネでなる支持台を取手用ポールの上端側に取り付け、鰐口状のクリップを支持台の内側に介装すると共に、クリップと支持台とを支軸で相対的にズレ動可能に軸着し、支持台の側板を引張り紐で拡開する操作レバーを取手用ポールの握り手側に取り付け、更に、略Ｌの字状を呈する突張りリンクを支持台の下部側からソケットケースまで伸びるよう取手用ポールの側面に支軸で軸着した直管型蛍光灯の着脱交換器具が知られている（特許文献５）。   In addition to the above, a support base made of a leaf spring bent in a substantially trapezoidal shape is attached to the upper end side of the handle pole, and a hook-shaped clip is interposed inside the support base, and the clip and the support base are supported on the support shaft. Attached to the grip handle side of the pole for the handle pole, and attached to the grip handle side of the handle pole. There is known a straight tube type fluorescent lamp attaching / detaching / replacement device that is pivotally attached to a side surface of a handle pole so as to extend from a lower side of the socket to a socket case (Patent Document 5).

その直管型蛍光灯の着脱交換器具は、蛍光灯の取外し時で説明すると、まず、クリップを半開き状態でガラス管にあてがい、取手用ポールがクリップと支持台との支軸点より突張りリンクの張出し側と反対方向に斜めになるよう保ち、突張りリンクの先端側を片側のソケットケースにあてがうと共に、ガラス管をクリップで把持し、次いで、取手用ポールを垂直方向に移動することにより、突張りリンクをソケットケースに圧接させてテコとすることから、ガラス管を把持したクリップにより灯全体を軸線方向に動かせて口金をソケットより取り外せるよう構成されている。   The straight tube type fluorescent lamp mounting / dismounting equipment will be explained when the fluorescent lamp is removed. First, the clip is half-opened and applied to the glass tube. The handle pole is a tension link from the pivot point of the clip and the support base. By keeping the slanting side opposite to the overhanging side, applying the tip end of the tension link to the socket case on one side, holding the glass tube with a clip, and then moving the handle pole vertically, Since the tension link is pressed against the socket case to make a lever, the entire lamp can be moved in the axial direction by a clip holding the glass tube so that the base can be removed from the socket.

その直管型蛍光灯の着脱交換器具では、上述したようにクリップを半開き状態でガラス管にあてがって取手用ポールの軸線方向を斜めに保つことにより、突張りリンクの上端側を片側のソケットケースにあてがうという不安定な手間の掛かる作業が必要となる。また、突張りリンクをソケットケースに圧接するテコ状態のままでソケットケースより擦り下げて灯全体をソケットから外すという無理な作業も必要となる。
特開平１０−２５５７１７ 実用新案登録第３０９９０６６号 特開平９−５７６４４ 特開平１０−５７２ 実用新案登録第３０１７８６２号 In the straight tube type fluorescent lamp attaching / detaching / replacement device, as described above, the clip is half-opened and applied to the glass tube, and the axial direction of the handle pole is kept oblique so that the upper end side of the tension link is connected to the socket case on one side. Unstable and time-consuming work is required. Further, it is necessary to perform an unreasonable work of removing the entire lamp from the socket by rubbing it down from the socket case while the lever link is in a state of being pressed against the socket case.

本願の請求項１に係る発明では、既設の蛍光灯を取り外すにあたり、作業者が具全体を取手用ポールで持って蛍光灯の装備場所まで持ち上げ、まず、プッシャの外端面を一方のソケットケースに当接し、これを基準面として具全体を押し上げると、チャックが蛍光灯のガラス管を湾曲爪の相対間に受け入れて把持すると共に、プッシャが蛍光灯のガラス管から口金を受け入れる。   In the invention according to claim 1 of the present application, when removing the existing fluorescent lamp, the operator holds the entire tool with the handle pole and lifts it up to the place where the fluorescent lamp is installed. First, the outer end face of the pusher is placed in one socket case. When the entire tool is pushed up with this contact as a reference surface, the chuck receives and grips the glass tube of the fluorescent lamp between the curved claws, and the pusher receives the base from the glass tube of the fluorescent lamp.

次いで、作業者が可動フレームを操作レバーで横桁フレームの一方の筒端より延長方向に伸び出させると、プッシャが一方の当接したソケットケースを押すことにより、具全体が蛍光灯のガラス管をチャックで挟持したままにプッシャと相対的にズレ動くことから、蛍光灯の灯全体により他方のソケットをソケットケースの内部に没入させると同時に、プッシャ側のソケットから口金ピンを含む口金を該ソケットより抜き出せる。 Then, when the operator is stretching out in the extending direction from the one of the cylindrical end of the crossbeam frame movable frame operating levers, by pressing the socket casing pusher is in contact one skilled, the glass tube of the total ingredients fluorescent lamp Since the other socket is immersed inside the socket case with the whole fluorescent lamp, the base including the base pin is inserted from the socket on the pusher side into the socket. It can be extracted more.

プッシャ側口金の外し状態では、他方の口金ピンを含む口金が没入側のソケットで保持されたままであるが、作業者が具全体を取手用ポールで引き下げることから、プッシャをソケットケースとの当接状態より摺り外し、蛍光灯のカラス管をチャックで挟持したまま口金ピンを含む口金をプッシャ側のソケットから外せば、灯全体をソケットケースより斜めに下ろせ、また、他方の口金ピンを含む口金を他方の没入したソケットより取り外せるから、チャックで挟持した蛍光灯を取手用ポールで手元まで取り寄せられる。   When the pusher side base is removed, the base including the other base pin is held by the socket on the immersive side, but the operator pulls down the entire tool with the handle pole, so the pusher comes into contact with the socket case. Remove the base including the pin from the socket on the pusher side while holding the fluorescent tube crow tube with the chuck, and lower the entire lamp diagonally from the socket case, and remove the base including the other base pin. Since it can be removed from the other immersed socket, the fluorescent lamp held by the chuck can be pulled to the hand with the handle pole.

蛍光灯の取付けにあたっては、まず、作業者がプッシャと片方の口金とを基準面の端面相互で合わせて蛍光灯のガラス管をチャックで把持することから蛍光灯を横桁フレームに予め組み付ける。次いで、作業者が取手用ポールを持って蛍光灯を装備場所まで持ち上げ、一方の口金ピンと相応するソケットの端子穴とを位置合わせし、口金ピンを端子穴に差し込み、プッシャを上部側から斜めにソケットケースにあてがうようレバー操作することによりソケットケースをプッシャで押すと、位置合せした一方の口金ピンを端子穴に差し込める。   When attaching the fluorescent lamp, first, the operator aligns the pusher and one of the bases at the end faces of the reference surface and grips the glass tube of the fluorescent lamp with the chuck, so that the fluorescent lamp is assembled in advance in the cross beam frame. Next, the operator lifts the fluorescent lamp with the handle pole to the installation location, aligns one of the cap pins with the corresponding socket terminal hole, inserts the cap pin into the terminal hole, and pushes the pusher diagonally from the top side. When the socket case is pushed with a pusher by operating the lever to fit the socket case, one of the aligned cap pins can be inserted into the terminal hole.

そのプッシャのあてがい状態より、作業者が上述したと逆にプッシャをソケットケースに対して摺り上げるよう取手用ポールを持ち上げると、プッシャがソケットケースを押すことから、具全体が蛍光灯のガラス管をチャックで挟持したままプッシャと相対的にズレ動き、蛍光灯の灯全体により先の口金ピンを位置合せした端子穴に差し込めると共に、ソケットをソケットケースの内部に没入させることにより、プッシャ側の口金を当該側のソケットと合わせられる。   When the operator lifts the handle pole so that the pusher is slid against the socket case, the pusher pushes the socket case. While moving between the pusher and the chuck, it is inserted into the terminal hole where the tip pin is aligned with the entire fluorescent lamp, and the socket on the pusher side is inserted into the socket case. Can be matched with the socket on that side.

プッシャ側の口金を当該側のソケットと合わせたら、作業者が操作レバーの握りを解除すると、可動フレームが引張バネで復帰方向に戻ると共に、プッシャが退却移動することから、先の口金ピンを端子穴に差し込んだソケットをソケットケースの内部で迫り出させられると同時に、プッシャ側の口金ピンを当該側のソケットの端子穴に差し込める。これにより、蛍光灯を装備場所に取り付けられ、作業者が具全体を取手用ポールで引き下げれば、チャック，プッシャを蛍光灯のガラス管より外すようにできる。   When the pusher base is aligned with the socket on that side, when the operator releases the grip of the operating lever, the movable frame returns to the return direction with the tension spring and the pusher moves backward, so the previous base pin is connected to the terminal. The socket inserted into the hole can be pushed out inside the socket case, and at the same time, the pusher side cap pin can be inserted into the terminal hole of the socket on the side. As a result, the fluorescent lamp can be attached to the equipment location, and if the operator pulls down the entire tool with the handle pole, the chuck and pusher can be detached from the glass tube of the fluorescent lamp.

その蛍光灯の取付け，取外しのいずれに際しても、チャックが蛍光灯のガラス管と擦れ動くことがなく、また、プッシャも蛍光灯のガラス管と摺接することがないため、ストレスをガラス管に加えないで、蛍光灯を簡単な操作で容易に着脱交換するようにできる。   When attaching or removing the fluorescent lamp, the chuck does not rub against the glass tube of the fluorescent lamp, and the pusher does not slide on the glass tube of the fluorescent lamp, so stress is not applied to the glass tube. Thus, the fluorescent lamp can be easily attached and detached with a simple operation.

チャックでは、横桁フレームの係止穴より筒内に挿置する支持枠の基軸部を支点に、蛍光灯のガラス管を把持する一対の湾曲爪を引張バネで離間乃至は近接可能に支持したことから、一対の湾曲爪により蛍光灯のガラス管を簡単な機構で安定よく把持できる。 In the chuck, a pair of curved claws that grip the glass tube of the fluorescent lamp are supported by a tension spring so as to be separated or close to each other with the base shaft portion of the support frame inserted into the cylinder from the locking hole of the cross beam frame as a fulcrum. Therefore, the glass tube of the fluorescent lamp can be stably held with a simple mechanism by the pair of curved claws.

このように構成する直管型蛍光灯の着脱交換器具では、既設の蛍光灯を取り外すにあたり、作業者が具全体を取手用ポール１で持って蛍光灯の装備場所まで持ち上げ、まず、図１３で示すようにプッシャ４の外側面を相対するソケットケースＮ２の前面にあてがい、それを基準面として具全体を押し上げると、チャック３，３’が蛍光灯のガラス管Ｇを一対の湾曲爪３ａ，３ｂの相対間に受け入れて把持すると共に、プッシャ４が蛍光灯の口金Ｃ２を非接触状態で受け入れる。 In the straight tube type fluorescent lamp attaching / detaching / changing apparatus configured as described above, when removing the existing fluorescent lamp, the operator lifts the entire tool with the handle pole 1 to the place where the fluorescent lamp is installed. as shown Ategai the outer surface of the pusher 4 in front of the opposite socket case N 2, pushing the entire ingredients it as a reference plane, the chuck 3, 3 'are a pair of glass tube G fluorescent lamp curved claws 3a, while gripping accept between 3b relative pusher 4 accepts a die C 2 of a fluorescent lamp in a non-contact state.

その作業に先立って、チャック３，３’の湾曲爪３ａ，３ｂは、図１４で示すように外しピン３５を湾曲爪３ａ，３ｂの相対する横桁フレーム２の上面側に突出させ、且つ、楔状片３４の各側部辺３４ｂ，３４ｃを横桁フレーム２の側面と各支持板３２のガイド縁３２ｃとの間に割り込ませて一対の湾曲爪３ａ，３ｂをキー３ｃで開いた状態に保つ。   Prior to the operation, the curved claws 3a and 3b of the chucks 3 and 3 'are removed as shown in FIG. 14 by causing the removal pin 35 to protrude to the upper surface side of the transverse beam 2 opposite to the curved claws 3a and 3b, and Each side edge 34b, 34c of the wedge-shaped piece 34 is inserted between the side surface of the cross beam frame 2 and the guide edge 32c of each support plate 32, and the pair of curved claws 3a, 3b are kept open with the key 3c. .

一対の湾曲爪３ａ，３ｂをキー３ｃで開いた状態に保ってから、上述したようにチャック３，３’を蛍光灯の装備場所まで持ち上げて蛍光灯のガラス管Ｇを互いに開いた湾曲爪３ａ，３ｂの間に受け入れると、蛍光灯のガラス管Ｇにより外しピン３５が押し下げられると共に、楔状片３ｃを横桁フレーム２の側面と各支持板３２のガイド縁３２ｃとの間より外し出せるから、図１５で示すように蛍光灯のガラス管Ｇを一対の湾曲爪３ａ，３ｂにより把持できる。このため、天井等の比較的高所に装備される蛍光灯でもチャック３，３’で簡単且つ確実に把持するようにできる。   After the pair of curved claws 3a and 3b are kept open with the key 3c, the curved claws 3a in which the chucks 3 and 3 'are lifted up to the place where the fluorescent lamp is installed and the glass tube G of the fluorescent lamp is opened to each other as described above. , 3b, the removal pin 35 is pushed down by the glass tube G of the fluorescent lamp, and the wedge-shaped piece 3c can be removed from between the side surface of the cross beam frame 2 and the guide edge 32c of each support plate 32. As shown in FIG. 15, the glass tube G of the fluorescent lamp can be held by the pair of curved claws 3a and 3b. For this reason, it is possible to easily and surely hold the fluorescent lamp mounted on a relatively high place such as the ceiling with the chucks 3 and 3 '.

チャック３，３’の開き保持と共に、プッシャ５は一対の囲いアームを５０ａ，５０ｂを支軸ピン５２ａ，５２ｂで開き状態に保つ（図６参照）。このプッシャ５では、蛍光灯のガラス管Ｇが囲いアーム５０ａ，５ｂの内端側に当接すると、各囲いアーム５ａ，５ｂの内面側が蛍光灯の口金と摺接しない略円形を呈するよう閉じる（図８参照）。これにより、蛍光灯が天井等の比較的高所に装備されている場合でも、プッシャ５が蛍光灯の口金Ｃ２を中央に取り込んでソケットケースＮ２に安定よく当接するようにできる。 Along with holding the chucks 3 and 3 'open, the pusher 5 keeps the pair of enclosing arms 50a and 50b open by the support pins 52a and 52b (see FIG. 6). In this pusher 5, when the glass tube G of the fluorescent lamp comes into contact with the inner end side of the surrounding arms 50a and 5b, the inner surface side of each of the surrounding arms 5a and 5b is closed so as to exhibit a substantially circular shape that does not slide on the base of the fluorescent lamp ( (See FIG. 8). Accordingly, even when the fluorescent lamp is equipped with a relatively high place such as a ceiling, it can be made to abut and stably in the socket case N 2 pusher 5 captures the ferrule C 2 of a fluorescent lamp in the center.

蛍光灯のガラス管Ｇをチャック３，３’で把持し、蛍光灯の口金Ｃ２をプッシャ５で取り込んだならば、図１６で示すように作業者が操作レバー９のレバー本体９を掴んで取手用ポール１の周面と近接方向に引くと、橋絡杆９ｂを介して可動環９１と共に、リール環９２が取手用ポールの周面に沿って下降し、図１７で示すように作動バー１１が牽引糸１０で引張られて下降すると共に、屈伸リンク１２が作動バー１１を斜めに倒しながら伸長する。 The glass tube G fluorescent lamp is gripped by the chuck 3, 3 ', if taken a die C 2 of a fluorescent lamp with a pusher 5, by grasping the lever main body 9 of the worker operating lever 9 as shown in FIG. 16 When pulled in the direction close to the peripheral surface of the handle pole 1, the reel ring 92 is lowered along the peripheral surface of the handle pole together with the movable ring 91 via the bridge 9 b, and as shown in FIG. 11 is pulled by the pulling thread 10 and descends, and the bending / extending link 12 extends while tilting the operating bar 11 diagonally.

屈伸リンク１２が伸長動すると、可動フレーム４が横桁フレーム２の一方の筒端より延長方向に伸び出し、プッシャ５が一方の当接したソケットケースＮ２を押し、図１８で示すように具全体が蛍光灯のガラス管Ｇをチャック３，３’で把持したままにプッシャ５と相対的にズレ動くことから、蛍光灯の灯全体により他方のソケットＳ１をソケットケースＮ１の内部に没入させる。これと同時に、プッシャ側のソケットＳ２から口金ピンＰ２を含む口金Ｃ２をソケットＳ２より抜き出せる。 When bending the link 12 is extended dynamic, movable frame 4 is out stretched in the extending direction from the one of the cylindrical end of the transverse girder frame 2, the pusher 5 presses the socket case N 2 in contact one skilled, ingredients as shown in FIG. 18 since the entire relative movement shift the pusher 5 to remain gripping the glass tube G of a fluorescent lamp in the chuck 3, 3 ', immersive by the overall lighting of the fluorescent lamp and the other of the socket S 1 to the inside of the socket casing N 1 Let At the same time, Nukidaseru a die C 2 containing base pins P 2 from the socket S 2 from the socket S 2 of the pusher side.

具全体がプッシャ５と相対的にズレ動くに伴って、ストッパ片７がソケットケースＮ１の前面に当接することから、蛍光灯の灯全体により他方のソケットＳ１をソケットケースＮ１の内部に安定よく没入できると同時に、プッシャ側のソケットＳ２から口金ピンＰ２を含む口金Ｃ２をソケットＳ２より確実に抜き出せる。この時に、位置決めバー８ではソケットケースＮ１の設置面に当接するＬ字状バー８ａ，８ｂをストッパ片７の各上端側に設けた円筒ホルダー７ａ，７ｂでスライドすることからズレ動く。 As the entire tool moves relative to the pusher 5, the stopper piece 7 comes into contact with the front surface of the socket case N 1 , so that the other socket S 1 is placed inside the socket case N 1 by the entire fluorescent lamp. at the same time, the stability may be immersive, Nukidaseru a die C 2 containing base pins P 2 reliably than the socket S 2 from the socket S 2 of the pusher side. When this, L-shaped bars 8a abutting the mounting surface of the socket casing N 1 in the positioning bar 8, a cylindrical holder 7a having a 8b on each upper side of the stopper piece 7 moves shifted from being slid in 7b.

プッシャ側の口金Ｃ２がソケットＳ２から外れた状態では、作業者が具全体を取手用ポール１でやや斜めにしながら引き下げれば、図１９で示すようにプッシャ５をソケットケースＮ２との当接状態より摺り外せ、蛍光灯のガラス管Ｇをチャック３，３’で挟持したまま口金ピンＰ２を含む口金Ｃ２をソケットケースＮ２より斜めに下ろせ、また、他方の口金ピンＰ１を含む口金Ｃ１を他方の没入したソケットＳ１より取り外せる。 In a state where the pusher side cap C 2 is detached from the socket S 2 , if the operator pulls down the entire tool while slightly tilting the handle pole 1 with the handle pole 1, the pusher 5 is connected to the socket case N 2 as shown in FIG. The base C 2 including the base pin P 2 can be lowered obliquely from the socket case N 2 while the glass tube G of the fluorescent lamp is held between the chucks 3 and 3 ′, and the other base pin P 1. removable from the socket S 1 that the mouthpiece C 1 and the other immersive including.

そのプッシャ５の摺外し途上で、口金ピンＰ２がソケットケースＮ２の下端縁から外れたならば、操作レバー９の握りを解除すると、可動フレーム４が引張バネ４ａで横桁フレーム２の筒内に退却移動すると共に、屈伸リンク１２が屈折状態に戻って作動バー１１を上方に引き上げる。作動バー１１が上方に引き上げられると、牽引糸１０を介して操作レバー９の可動環側９１，９２を含む操作レバー９が復帰動する。 In sliding off the course of the pusher 5, if the cap pins P 2 is detached from the lower edge of the socket case N 2, when releasing the grip of the operating lever 9, the tubular crossbeam frame 2 by the movable frame 4 tension spring 4a The retractable link 12 returns to the refracted state and the operating bar 11 is pulled upward while retreating inward. When the operation bar 11 is pulled upward, the operation lever 9 including the movable ring sides 91 and 92 of the operation lever 9 returns through the pulling thread 10.

蛍光灯の取付けにあたっては、まず、作業者がプッシャ５の外側面と片方の口金Ｃ２とを基準面の端面相互で合わせて蛍光灯のガラス管Ｇをチャック３，３’で把持することから蛍光灯を横桁フレーム２に予め組み付ける。 When installing the fluorescent lamp, first, a glass tube G fluorescent lamp combined operator at the end face each other of the outer surface and one of the base C 2 and the reference surface of the pusher 5 be gripped by the chuck 3, 3 ' A fluorescent lamp is assembled in advance in the cross beam frame 2.

次いで、取手用ポール１を持って蛍光灯を装備場所まで持ち上げ、具全体から蛍光灯を斜めに保って一方の口金ピンＰ１と相応するソケットＳ１の端子穴とを位置合わせする。この際には、位置決めバー８の金属バー８ａ，８ｂをソケットケースＮ１の両側部から設置面に向けて当接することから、蛍光灯を天井等の比較的高所に取り付けるにも、ストッパ片７の当接する側の口金Ｃ１とソケットＳ１とを容易に位置合わせできる（図１９参照）。 Next, holding the handle pole 1, the fluorescent lamp is lifted up to the installation location, and the fluorescent lamp is held obliquely from the entire tool to align one of the cap pins P 1 and the corresponding terminal hole of the socket S 1 . At this time, metal bars 8a of the positioning bar 8, 8b from coming into contact toward the installation surface from both sides of the socket case N 1, to attach the fluorescent lamp to a relatively high place such as a ceiling, a stopper piece 7 can be easily aligned with the base C 1 on the side in contact with the socket S 1 (see FIG. 19).

口金Ｃ１とソケットＳ１とを位置合わせしたならば、作業者が操作レバー９を軽く握りながらことから、プッシャ５を上部側の面取り部５０ａ，５０ｂから斜めにソケットケースＮ２の下端縁にあてがう。このプッシャ５のあてがい状態より、作業者が操作レバー９の握りを強めながら、上述したと逆に、プッシャ５をソケットケースＮ２に対して摺り上げるよう取手用ポールを持ち上げる。これにより、口金ピンＰ１をソケットＳ１の端子穴に差し込めると共に、プッシャ５をソケットケースＮ２の前面にあてがえる。 When the base C 1 and the socket S 1 are aligned, the pusher 5 is obliquely moved from the upper chamfered portions 50a and 50b to the lower end edge of the socket case N 2 because the operator holds the operation lever 9 lightly. Apply. From the applied state of the pusher 5, the operator lifts the handle pole so as to slide the pusher 5 against the socket case N 2 , contrary to the above, while strengthening the grip of the operation lever 9. Ategaeru Thereby, to plug the base pins P 1 to the terminal holes in the socket S 1, the pusher 5 to the front of the socket case N 2.

そのプッシャ５のあてがい状態では、プッシャ５がソケットケースＮ２を押すことから、具全体が蛍光灯のガラス管Ｇをチャック３，３’で挟持したままプッシャ５と相対的にズレ動き、蛍光灯の灯全体により先の口金ピンＰ１を位置合せした端子穴に差し込めてソケットＣ１をソケットケースＮ１の内部に没入させると共に、プッシャ側の口金ピンＰ２を含む口金Ｃ２を当該側のソケットＳ２と位置合わせできる。 In the applied state of the pusher 5, the pusher 5 pushes the socket case N 2 , so that the entire tool is displaced relative to the pusher 5 while holding the glass tube G of the fluorescent lamp between the chucks 3 and 3 ′. of the entire lamp socket C 1 to fit into the terminal hole to align the previous base pins P 1 together is retracted into the interior of the socket case N 1, the mouthpiece C 2 containing base pins P 2 of the pusher side of the side It can be aligned with the socket S 2.

プッシャ側の口金Ｃ２を当該側のソケットＳ２と合わせたら、作業者が操作レバーＰの握りを解除すると、上述したように可動フレーム４，屈伸リンク１２，作動バー１１を含む操作レバー９までが引張バネ４ａで復帰方向に戻ると共に、プッシャ５が退却移動することから、先の口金ピンＰ１を端子穴に差し込んだソケットＳ１をソケットケースＮ１の内部で迫り出させられると同時に、プッシャ側の口金ピンＰ２を当該側のソケットＳ２の端子穴に差し込める。 When the pusher side cap C 2 is aligned with the socket S 2 on the side, when the operator releases the grip of the operation lever P, the operation lever 9 including the movable frame 4, the bending link 12 and the operation bar 11 as described above is reached. There together back to the return direction at a tension spring 4a, since the pusher 5 is retracted moves and brought Seridasa the socket S 1 to inserting the tip of base pins P 1 to the terminal hole inside the socket casing N 1 at the same time, Sashikomeru the base pins P 2 of the pusher side to the terminal holes in the socket S 2 of the side.

これにより、蛍光灯を高所の装備場所にも取り付けられ、作業者が具全体を取手用ポール１で引き下げれば、チャック３，３’、プッシャ５を蛍光灯より外すようにできる。その蛍光灯の取付け，取外しのいずれに際しても、チャック３，３’が蛍光灯のガラス管Ｇと擦れ動くことがなく、また、プッシャ５も蛍光灯のガラス管Ｇと摺接することがないため、ストレスをガラス管Ｇに加えないで、蛍光灯を簡単な操作で容易に着脱交換するようにできる。   As a result, the fluorescent lamp can be attached to a high-equipment place, and if the operator pulls down the entire tool with the handle pole 1, the chucks 3, 3 'and the pusher 5 can be removed from the fluorescent lamp. When attaching or removing the fluorescent lamp, the chucks 3 and 3 ′ do not rub against the glass tube G of the fluorescent lamp, and the pusher 5 does not slide on the glass tube G of the fluorescent lamp. Without applying stress to the glass tube G, the fluorescent lamp can be easily attached and detached with a simple operation.

取手用ポール１を長尺なものに代えるには、ホールホルダー１３の締付けねじ１３ａを弛めて既設の取手用ポール１を取り外せば、別のものに代えられる。これと共に、操作レバー９締付けねじ９０ｂを緩めて操作レバー９を前の取手用ポール１から取り外し、牽引糸１０を巻き戻すことから取り替えた取手用ポールに取付け直し、牽引糸１０の長さを調整すればよい。   In order to replace the handle pole 1 with a long one, the fastening screw 13a of the hole holder 13 is loosened and the existing handle pole 1 is removed. At the same time, loosen the operating lever 9 tightening screw 90b, remove the operating lever 9 from the previous handle pole 1, rewind the traction thread 10 and reattach it to the replaced handle pole, and adjust the length of the traction thread 10 do it.

上述した実施の形態では、可動フレーム４から操作レバー９の復帰動を可動フレーム４の引張バネ４ａで行わせる場合に基づいて説明したが、例えば作動バー１１の繋ぎピン１１ｂとポールホルダー１３または横桁フレーム２との間に掛け渡す引張バネを加えるようにできる。   In the above-described embodiment, the description has been made based on the case where the return movement of the operation lever 9 from the movable frame 4 is performed by the tension spring 4 a of the movable frame 4. A tension spring that spans between the girder frames 2 can be added.
