Description

直管型蛍光灯の着脱交換器具Straight tube type fluorescent lamp attachment and detachment exchange equipment
　本発明は、天井等の比較的高所に設置される直管型蛍光灯を取手用ポールによる遠隔操作で着脱交換する器具に関するものである。 The present invention relates to a device for attaching and detaching a straight tube fluorescent lamp installed at a relatively high place such as a ceiling by remote control using a handle pole.
　直管型蛍光灯は、図１で示すように各ソケットＳ１，Ｓ２をバネ変位可能に収容した左右のソケットケースＮ１，Ｎ２を天井カバーＲの内側に備え、各口金Ｃ１，Ｃ２を各ソケットＳ１，Ｓ２の前面側に当接すると共に、相平行した二本の各端子ピンＰ１，Ｐ２を各ソケットＳ１，Ｓ２の水平方向に並ぶ二つの端子穴に差し込んで電気的に接続し、ガラス管Ｇを各ソケットＳ１，Ｓ２の間に掛け渡すことにより天井等に取り付けられている。
　以下、直管型蛍光灯の構成を「ガラス管」、「口金」、「端子ピン」、「ソケットケース」、「ソケット」、「端子穴」と単に表現する。
　本出願人は、先に、天井等の比較的高所に設置される直管型蛍光灯の着脱交換器具（以下、「従来例」という。）を提案した（日本特許出願公開番号：特開２００８−１９２４５７）。
　従来例は、長尺な直線状の取手用ポールと、取手用ポールの上端部で直交方向に亘る略四角筒形の横桁フレームをベースに、次のような各部を備えて構成されている。
　本器具については、取手用ポール，横桁フレームが呈する形状のＴ字側から見て「正面」といい、横桁フレームを正面から見た「前後」を「前後」といい、奥行き方向を「幅方向」といい、「上下」を「上下」乃至は「縦」、横桁フレームを上側から下側に見て「平面」といい、左側または右側から見て「側面」という。
　横桁フレームは、ガラス管を受止め可能なガラス管の径と略相応した幅を有する断面略四角筒状に形成されている。横桁フレームには、ガラス管を抱込み保持乃至は解放可能な二つのチャック具が横桁フレームの長手方向に間隔を隔てて備え付けられている。各チャック具は、ガラス管を抱込み保持乃至は解放する爪上部側が横桁フレームの幅方向で相向き合う一対の挟持爪で組み立てられている。
　一対の挟持爪は、横桁フレームの幅方向に亘って爪下寄りの間に掛け渡す引張りバネで引合い支持することにより、爪上部側が閉じ状態を保つよう取り付けられている。挟持爪には、爪上部側の閉じ状態から開き状態に変え、開き状態から閉じ状態に戻せるロックが組み付けられている。
　ロックは、側面上向きコの字状に形成されている。ロックは、下部辺と横桁フレームの下部面との間に間隔を保ち、前後部辺が横桁フレームの幅方向両側に位置することによりスライド可能に嵌め合わされている。ロックには、横桁フレームの下部側より上部側に向けて挿通する押下げピンが下部辺の中央で縦に立てて設けられている。押下げピンは、横桁フレームの下部面との間に保った間隔分だけ、ロック全体を横桁フレームの幅方向両側に沿って押し上げると、横桁フレームの上部面より挟持爪の相対間に突出する長さを有する。
　ロックは、前後部辺を横桁フレームの上部面より上方に突出させて閉じ状態にある挟持爪の間に割り込ませると、挟持爪を引張りバネに抗して開き状態に保つ。一方、開き状態にある挟持爪の間で、横桁フレームの上部面より上方に突出する押下げピンをガラス管との当接で横桁フレームの上部面まで押し下げると、ロックは挟持爪の間から外れて挟持爪を引張りバネで閉じ状態に戻す。
　横桁フレームには、筒片端より延長方向外方に迫出し可能な可動フレームが設けられている。可動フレームは、片端部を横桁フレームの筒外に露出させて筒内に収容されている。また、横桁フレームの筒内に取り付けた引張りバネにより筒内の退却方向に引張支持されている。
　可動フレームの露出する端部側には、プッシャ具が設けられている。プッシャ具は、片方の口金付近を相対的にズレ動き可能に受け入れ、また、ソケットケースの前面側と当接可能に備え付けられている。プッシャ具は、二つが横桁フレームの幅方向で向き合い、ガラス管の径より大きな側面円形の空間を呈する一対の円弧枠で組み立てられている。一対の円弧枠は、正面上向きコの字状の立付けブラケットに軸承装着することにより上部側から開き，閉じ可能に取り付けられている。立付けブラケットは、可動フレームに取付け固定されている。
　可動フレームは、横桁フレームの筒内に配置された偏心カムで内端側から押圧することにより、引張りバネに抗して横桁フレームの筒片端から延長方向外方に迫出し可能に取り付けられている。偏心カムは、取手用ポールの上端部に植立した支軸で保持されている。偏心カムの支軸は、横桁フレームの下部面より筒内に挿置することにより、偏心カムの偏心基部に埋込み装着されている。また、横桁フレームの下部面と上部面で回転可能に軸受け支持されている。
　この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場合、ロックの前後部辺が横桁フレームの上部面より上方に突出するよう、作業員がロックを押し上げ、前後部辺を先端側より閉じ状態にある各挟持爪の間に割り込ませる。そのロックの押上げに伴って、押下げピンが横桁フレームの上部面より挟持爪の相対間に突出する。これにより、挟持爪を開き状態に保つ。また、作業員がプッシャ具を開き状態にする。
　チャック具，プッシャ具を開き状態に保ち、作業員が具全体を取手用ポールで蛍光灯の設置場所まで持ち上げる。
　具全体の持上げ状態では、可動フレームを横桁フレームの筒内に退却状態のままとし、作業員が具全体を取手用ポールで操作し、プッシャ具を片側の口金近くに押し付け、片側の口金を円弧枠の開き状態にある内側に取り込んでプッシャ具を閉じ状態にする。それと共に、プッシャ具をソケットケースの前面側に当てて具全体を位置決めする。また、ガラス管を開き状態にある挟持爪の間に受け入れ、作業員が具全体を更に持ち上げてガラス管を押下げピンに押し付ける。このガラス管の押付けに伴って、押下げピンが横桁フレームの上部面まで下がり、ロックが開き状態にある挟持爪の間より横桁フレームの上部面にまで落ち込む。これにより、挟持爪が引張りバネで閉じ、各チャック具がガラス管を挟持爪の間に抱込み保持する。
　ガラス管を各チャック具で抱込み保持したならば、作業員が取手用ポールの全長を軸回り方向に回転させて偏心カムを旋回し、可動フレームを偏心カムで横桁フレームの筒片端から延長方向外方に迫り出させる。この可動フレームの迫出しにより、プッシャ具が当該側のソケットケースを押圧する。プッシャ具がソケットケースを前面側より押圧すると、各チャック具で抱込み保持した灯全体を含む具全体がプッシャ具と相対的にズレ動き、灯全体による押圧により、プッシャ側と反対側のソケットがソケットケースの内部に没入変位する。一方で、プッシャ具で押圧しているソケット側の端子ピンがソケットの端子穴から抜け出る。
　プッシャ側の端子ピンがソケットの端子穴より抜け出た状態から、取手用ポールを回転状態に保ったまま、具全体を取手用ポールでやや斜めの姿勢にし、プッシャ側と反対側のソケットをソケットケースの内側でバネ変位により斜めに没入させる。その具全体を斜め姿勢にすると共に、ソケットの没入状態を保ち、具全体を斜め姿勢にしたまま取手用ポールでプッシャ側から引き下げることにより、プッシャ具を当該側のソケットケースから外し出す。
　プッシャ具が当該側のソケットケースより外れると、作業員の取手用ポールによる操作でプッシャ側と反対側の端子ピンもソケットの端子穴から抜き出せる。
　このような手順により、ガラス管を両チャック具で抱込み保持したまま具全体を取手用ポールで下ろせば、蛍光灯を作業員の手元まで持ち運べる。更に、作業員が各挟持爪を手元で開らくと、蛍光灯をチャック具から取り外せる。
　新規の蛍光灯を取り付ける場合、作業員がロックを横桁フレームの上部面より上方に動かし、ロックを挟持爪の間に割り込ませて挟持爪を開き状態に保つ。次に、プッシャ具の外端辺（ソケットケースとの当接側）を基準面とし、口金の端面をプッシャ具の外端辺と合わせ、当該側の端子ピンをプッシャ具の外端辺より外方に突出させた状態で、片側の口金をプッシャ具の内側に位置し、ガラス管を開き状態にある挟持爪の間に位置させてセットする。その後に、上述したと同様に、押下げピンを含むロックを横桁フレームの上部面まで落ち込ませる。これにより、ガラス管を両チャック具で抱込み保持させ、ガラス管を横桁フレームの上部面に位置決めセットする。その蛍光灯のセット状態から、作業員が具全体を取手用ポールで蛍光灯の取付け場所まで持ち上げる。
　具全体の持上げ状態では、まず、具全体を取手用ポールでやや斜めに保ち、プッシャ側と反対側の端子ピンをソケットの端子穴と位置合わせて差し込む。次に、作業員が端子ピンを差し込んだソケットを灯全体で斜めに没入変位させるよう取手用ポールによる操作で押しながら、プッシャ具をソケットケースの下部近くに接近させ、更に、プッシャ具の上部側をソケットケースの前面側に当接させてズラし上げる。
　その後に、作業者が取手用ポールを軸回り方向に回転させて偏心カムを旋回し、可動フレームを偏心カムで押圧し迫り出させると共に、具全体を水平状態に保ってプッシャ具を全体的にソケットケースの前面側に合わせて押し当てる。
　これにより、上述したと同様にチャック具で抱込み保持した灯全体を含む具全体をプッシャ具と相対的にズレ動かせるから、プッシャ側と反対側のソケットを灯全体で没入変位させる。一方で、プッシャ側の端子ピンをソケットの端子穴と位置合わせするようにできる。
　プッシャ側の端子ピンをソケットの端子穴に位置合せしたならば、作業者が取手用ポールの軸回り回転を元に戻すと、灯全体を含む具全体が可動フレームの退却により相対的にズレ動く。このズレ動きに伴って、プッシャ側と反対側のソケットがソケットケースの内部で迫出し変位すると共に、プッシャ側の端子ピンをソケットの端子穴に差し込める。これにより、蛍光灯をソケットの間に掛渡し装着できる。
　この後は、作業者が具全体を取手用ポールで引き下げることから、挟持爪を引張りバネに抗してガラス管と強制的にズラしながら開かせることにより、各チャック具を蛍光灯より外せるようにできる。
　従来例では、蛍光灯の取外し時に、また、新規な蛍光灯の取付け時にも同様に、作業者が取手用ポールを手で持って具全体を天井等の高所まで差し上げると共に、顔を上に向けて様子を見ながら長尺な取手用ポールの全長を軸回り方向に回転することによる可動フレームの迫出し操作が必要となる。
　これでは、具全体を取手用ポールで天井等の高所にまで差し上げて顔を上向きに、取手用ポールの全長を軸回り方向に回転するという不安定な操作，作業が要求される。
　新規の蛍光灯を横桁フレームの上部面にセットする際には、二本の端子ピンをソケットの端子穴と整合する向きに合わせ、また、プッシャ具の外端辺より突出する端子ピンの長さを定めるに、作業員の堪，目分量により行うことが要求される。これでは、必ずしも端子ピンの突出位置乃至は向きを正確に定められるとは限らない。
　新規な蛍光灯の取付け後には、作業者が具全体を取手用ポールで引き下げることにより、一対の挟持爪を引張りバネに抗してガラス管と強制的にズラし開かせることが必要となる。これでは、チャック具を蛍光灯より外す際に、ガラス管に対するチャック具の擦れ力が加わるおそれがある。 As shown in FIG. 1, the straight tube type fluorescent lamp includes left and right socket cases N 1 and N 2 in which the sockets S 1 and S 2 are housed so as to be spring-displaceable inside the ceiling cover R, and the caps C 1 , C 2 is brought into contact with the front side of each of the sockets S 1 and S 2 , and two parallel terminal pins P 1 and P 2 are arranged in two terminal holes arranged in the horizontal direction of the sockets S 1 and S 2. The glass tube G is attached to a ceiling or the like by being inserted and electrically connected and spanning between the sockets S 1 and S 2 .
Hereinafter, the configuration of the straight tube fluorescent lamp is simply expressed as “glass tube”, “cap”, “terminal pin”, “socket case”, “socket”, “terminal hole”.
The present applicant has previously proposed a detachable and replaceable appliance for a straight tube type fluorescent lamp (hereinafter referred to as “conventional example”) installed in a relatively high place such as a ceiling (Japanese Patent Application Publication Number: JP 2008-192457).
The conventional example is composed of a long linear handle pole and a substantially square cylindrical cross beam frame extending in the orthogonal direction at the upper end of the handle pole, and including the following parts. .
This instrument is called “front” when viewed from the T-shaped side of the handle pole and cross beam frame, “front” and “front” when the cross frame is viewed from the front, and the depth direction is “ It is called “width direction”, “up and down” is called “up and down” or “vertical”, the horizontal beam frame is called “plane” when seen from the upper side to the lower side, and “side” when seen from the left or right side.
The cross beam frame is formed in a substantially rectangular tube section having a width substantially corresponding to the diameter of the glass tube capable of receiving the glass tube. The cross beam frame is provided with two chucks which can hold and release the glass tube at a distance in the longitudinal direction of the cross beam frame. Each chuck is assembled with a pair of clamping claws in which the upper claw side for holding and releasing the glass tube faces each other in the width direction of the cross beam frame.
The pair of clamping claws are attached so that the upper side of the claw is kept closed by being attracted and supported by a tension spring that extends between the width of the cross girder frame and below the claw. A lock that can be changed from the closed state on the upper side of the nail to the open state and returned from the open state to the closed state is assembled to the clamping nail.
The lock is formed in a U-shape that faces upward. The lock is fitted so as to be slidable by maintaining a gap between the lower side and the lower surface of the cross beam frame and by positioning the front and rear sides on both sides in the width direction of the cross beam frame. The lock is provided with a push-down pin which is inserted vertically from the lower side of the cross beam frame toward the upper side at the center of the lower side. When the entire lock is pushed up along the width direction of the cross beam frame by the distance kept between the lower pin and the lower surface of the cross beam frame, It has a protruding length.
The lock keeps the holding claw open against the tension spring when the front and rear sides protrude above the upper surface of the cross beam frame and are inserted between the holding claws in the closed state. On the other hand, when the push pin protruding upward from the upper surface of the cross beam frame is pushed down to the upper surface of the cross beam frame between the holding claws in the open state and brought into contact with the glass tube, the lock is held between the holding claws. Remove the nail and return it to the closed state with a tension spring.
The cross beam frame is provided with a movable frame that can be pushed outward in the extending direction from one end of the cylinder. The movable frame is accommodated in the cylinder with one end portion exposed to the outside of the horizontal girder frame. Moreover, it is tension-supported in the retreat direction in the cylinder by a tension spring attached in the cylinder of the cross beam frame.
A pusher tool is provided on the exposed end side of the movable frame. The pusher device is provided so as to be able to move relatively in the vicinity of one of the caps and to come into contact with the front side of the socket case. The two pusher devices are assembled in a pair of arc frames that face each other in the width direction of the cross frame and present a side circular space larger than the diameter of the glass tube. The pair of arc frames are attached so as to be openable and closeable from the upper side by attaching to a front-facing U-shaped standing bracket. The standing bracket is fixedly attached to the movable frame.
The movable frame is attached so that it can be pushed outward from the tube end of the cross beam frame against the tension spring by pressing it from the inner end side with an eccentric cam arranged in the tube of the cross beam frame. ing. The eccentric cam is held by a support shaft planted at the upper end of the handle pole. The support shaft of the eccentric cam is embedded in the eccentric base portion of the eccentric cam by being inserted into the cylinder from the lower surface of the cross beam frame. In addition, the lower and upper surfaces of the cross beam frame are rotatably supported by bearings.
With this straight tube fluorescent lamp attachment / detachment and replacement tool, when removing an existing fluorescent lamp, an operator pushes up the lock so that the front and rear sides of the lock protrude above the upper surface of the cross beam frame, and the front and rear sides are It is inserted between each nail that is in the closed state from the tip side. As the lock is pushed up, the push-down pin protrudes from the upper surface of the cross beam frame between the nail claws. Thereby, a clamping nail is maintained in an open state. The worker opens the pusher device.
The chuck and pusher are kept open, and the operator lifts the entire tool up to the place where the fluorescent lamp is installed using the pole for handling.
In the lifting state of the entire tool, the movable frame remains in the state of being retracted into the tube of the cross beam frame, the operator operates the entire tool with the handle pole, presses the pusher tool near the base on one side, and pushes the base on the one side. Take in the inside of the arc frame in the open state and close the pusher tool. At the same time, the pusher tool is applied to the front side of the socket case to position the entire tool. Further, the glass tube is received between the holding claws in the open state, and the worker further lifts the entire tool and presses the glass tube against the push-down pin. As the glass tube is pressed, the push-down pin is lowered to the upper surface of the cross beam frame, and is dropped to the upper surface of the cross beam frame from between the holding claws in which the lock is open. As a result, the clamping claws are closed by the tension spring, and each chucking tool holds the glass tube between the clamping claws.
If the glass tube is held by each chuck, the operator rotates the entire length of the handle pole in the direction of the axis to turn the eccentric cam, and the movable frame is extended from one end of the horizontal girder frame with the eccentric cam. The direction is pushed outward. The pusher presses the socket case on the side by the protrusion of the movable frame. When the pusher tool presses the socket case from the front side, the entire tool, including the entire lamp held by each chuck tool, moves relative to the pusher tool, and the socket on the opposite side of the pusher side is moved by the pressure of the entire lamp. Immersion displacement inside the socket case. On the other hand, the terminal pin on the socket side pressed by the pusher tool comes out of the terminal hole of the socket.
With the terminal pin on the pusher side pulled out of the terminal hole of the socket, keep the handle pole in a rotating state, and take the entire tool with the handle pole in a slightly slanted position, and the socket on the opposite side to the pusher side in the socket case. Immerse diagonally by spring displacement inside. The entire tool is placed in an oblique position, the socket is kept immersed, and the pusher tool is removed from the socket case on the side by pulling it down from the pusher side with the handle pole while keeping the entire tool in the oblique position.
When the pusher tool is removed from the socket case on that side, the terminal pin on the side opposite to the pusher side can be extracted from the terminal hole of the socket by the operation of the operator's handle pole.
With such a procedure, the fluorescent lamp can be carried to the operator's hand if the entire tube is taken down by the handle pole while the glass tube is held by both chuck devices. Furthermore, when the operator opens each clamping claw with his hand, the fluorescent lamp can be removed from the chuck.
When installing a new fluorescent lamp, the operator moves the lock upward from the upper surface of the cross beam frame, interrupts the lock between the holding claws, and keeps the holding claws open. Next, use the outer edge of the pusher tool (the side that contacts the socket case) as the reference plane, align the end face of the base with the outer edge of the pusher tool, and place the terminal pin on the side outside the outer edge of the pusher tool. With the base protruding, the base on one side is positioned inside the pusher, and the glass tube is positioned between the holding claws in the open state. Thereafter, as described above, the lock including the push pin is lowered to the upper surface of the cross beam frame. As a result, the glass tube is held and held by both chucks, and the glass tube is positioned and set on the upper surface of the cross beam frame. From the set state of the fluorescent lamp, the operator lifts the entire tool to the place where the fluorescent lamp is installed with the handle pole.
In the lifting state of the entire tool, first hold the entire tool at a slight angle with the handle pole, and insert the terminal pin on the opposite side of the pusher into alignment with the terminal hole of the socket. Next, the operator pushes the pusher tool close to the bottom of the socket case while pushing the handle with the handle pole so that the socket into which the terminal pin is inserted is obliquely immersed and displaced throughout the lamp. Slide it up against the front side of the socket case.
After that, the operator rotates the handle pole in the direction around the axis to turn the eccentric cam, presses the movable frame with the eccentric cam and pushes it out, and keeps the entire tool in a horizontal state and the pusher tool as a whole. Press it according to the front side of the socket case.
Accordingly, as described above, the entire tool including the entire lamp held and held by the chuck tool can be displaced relative to the pusher tool, so that the socket on the opposite side to the pusher side is immersed and displaced throughout the lamp. On the other hand, the pusher side terminal pin can be aligned with the terminal hole of the socket.
If the terminal pin on the pusher side is aligned with the terminal hole of the socket, when the operator returns the rotation around the axis of the handle pole to the original position, the entire tool, including the entire lamp, moves relatively by retraction of the movable frame. . Along with this displacement movement, the socket on the opposite side to the pusher side is pushed out and displaced inside the socket case, and the terminal pin on the pusher side is inserted into the terminal hole of the socket. As a result, the fluorescent lamp can be mounted between the sockets.
After this, since the operator pulls down the entire tool with the handle pole, each chuck tool can be removed from the fluorescent lamp by forcing the clamping claws to open against the glass spring against the tension spring. Can be.
In the conventional example, when removing the fluorescent lamp or when installing a new fluorescent lamp, the operator holds the handle pole with his hand and raises the entire tool to a high place such as the ceiling, with the face up. It is necessary to push out the movable frame by rotating the entire length of the long handle pole in the direction of the axis while looking at it.
This requires an unstable operation and work in which the entire tool is lifted up to a high place such as the ceiling with a handle pole, the face is turned upward, and the entire length of the handle pole is rotated about the axis.
When setting a new fluorescent lamp on the top surface of the cross beam frame, align the two terminal pins with the socket so that they are aligned with the socket terminal holes, and the length of the terminal pins protruding from the outer edge of the pusher In order to determine the length, it is required to perform according to the skill of the worker. In this case, the protruding position or direction of the terminal pin is not necessarily determined accurately.
After the installation of the new fluorescent lamp, it is necessary for the operator to pull down the entire tool with the handle pole so that the pair of clamping claws are forcibly displaced from the glass tube against the tension spring and opened. In this case, when the chuck is removed from the fluorescent lamp, there is a possibility that the rubbing force of the chuck against the glass tube is applied.

　本発明に係る直管型蛍光灯の着脱交換器具は、長尺な直線状の取手用ポールと、取手用ポールの上部側で直交方向に亘る横断面略Ｃ形の横桁フレームと、更に、横桁フレームの幅方向で相対する二枚の基体ブラケットをベースに構成されている。
　取手用ポールは、ステンレス等の金属製丸パイプで形成されている。取手用ポールは、横桁フレームの長手方向略中央に配置されている。
　横桁フレームは、ガラス管の径と略同じ幅を有し、下部面を長手方向に沿って開放したステンレス等のＣ字鋼で形成されている。横桁フレームは、具全体を軽量化するべく、蛍光灯の長さよりも短い長さに形成されている。
　基体ブラケットは横桁フレームの略中央から下方に張り出す略逆台形の板部材でなり、広幅な上辺側を横桁フレームの前面，後面にあてがい固定することにより横桁フレームに取り付けられている。
　横桁フレームには、次のようなチャック具，可動フレームが設けられている。
　チャック具は、蛍光灯のガラス管を抱込み乃至は解放するもので、横桁フレームの中央位置より略等間隔を長手方向に隔て二つ設けられている。各チャック具は、横桁フレームの幅方向で相向き合う一対の挟持爪を備えて組み立てられている。一対の挟持爪は、通常時は閉じ状態に引張りバネで引合い支持することにより、爪上部側より開き，閉じ可能に取り付けられている。引張りバネは、横桁フレームの幅方向に亘って各挟持爪の中腹辺より下寄りに掛け渡されている。
　各チャック具には、引張りバネの掛渡し位置より上方の相対間に割り込んで各挟持爪を閉じ状態から開き状態に変えるロックが組み付けられている。
　ロックは、横桁フレームより縦長で桁全体を幅方向で囲い込む略四辺形の枠状に形成されている。挟持爪の閉じ状態では、ロックは下部辺と横桁フレームの下部面との間に間隔を保っている。ロックは、下部辺が横桁フレームの下部面と当接するまで上方に押し上げると、引張りバネの掛渡し位置より上方で挟持爪の相対間に割り込むことにより、挟持爪を開き状態に保つ。一方、開き状態にある各挟持爪の間に受け入れるガラス管で上部辺から押し下げて挟持爪の間から外すことにより、挟持爪を閉じ状態に戻せる。
　可動フレームは、金属製の丸パイプで形成されている。可動フレームは、片端部を横桁フレームの桁片端より外に露出し、横桁フレームの桁片端から延長方向外方に迫出し移動するよう横桁フレームの内部に収容されている。また、横桁フレームの内部で可動フレームの軸線上に備えるスプリングにより桁内の退却方向にバネ支持されている。

　位置決めセット具は、プッシャ具の立付けブラケットに取り付けられている。立付けブラケットには、一対の円筒部が可動フレームの端部側に位置するブラケット板の両側辺を湾曲させて設けられている。位置決めセット具は、各支軸部を立付けブラケットの円筒部に挿通することにより上下にスライド可能に保持されている。
　位置決めセット具は、蛍光灯を横桁フレームの上部側にセットする際、支軸部より連続する基軸部の屈曲部が立付けブラケットの円筒下端と当接するまで上方にスライドさせて位置されている。その位置決めセット具には、二本の端子ピンを付当て軸部の軸上辺に平行に載せると共に、口金の端面を付当て軸部の軸上辺に当接させることにより、端子ピンの突出向き並びにプッシャ具の外端辺（ソケットケースとの当接側）を基準とする端子ピンの突出長さを定められる。ガラス管をチャック具で抱え込んで蛍光灯を横桁フレームの上部側にセットした状態で端子ピンの突出向き乃至は突出長さがバラ付いていると、端子ピンをソケットの端子穴に合わせて差し込めない事態が生ずる。
　端子ピンの位置決め後は、位置決めセット具は立付けブラケットの円筒部で下方にスライドすれば、端子ピンをソケットの端子穴に差し込む際の邪魔とならないよう退却させられる。
　取手用ポールは、ポール上端側が基体ブラケットの間から横桁フレームの桁内に挿置されている。取手用ポールは、基体ブラケットの間に挿置するポール部分が基体ブラケットの下部寄り板間に掛渡し固定する枢軸ピンで基体ブラケットの板面に軸承装着されている。

　一対の挟持爪がガラス管を抱え込んだ閉じ状態、即ち、ロックが挟持爪の間より外れた状態にあるとき、押上げレバーを操作環で引張り操作すると、各レバーアームが上方に揺動し、ロックを各レバーアームで押し上げて挟持爪の間に割り込ませることにより、挟持爪が閉じ状態から開き状態に変えられる。 The problem of the present invention is that the operator holds the handle pole by hand and supports the entire tool, directs only the face to the place where the fluorescent lamp is installed, and moves the movable frame to the cross beam frame by simple operation of the handle pole. It is configured so that it can be moved outwardly in the extending direction from one end of the spar.
When installing a new fluorescent lamp, hold the glass tube with a pair of clamping claws and position and set it on the upper surface of the cross beam frame. The direction of the terminal pin with respect to the terminal hole and the terminal pin from the outer edge of the pusher It is possible to easily position and set by accurately matching the protruding positions of the two.
After the attachment of the new fluorescent lamp, the holding claw in the holding state of the glass tube (closed state of the holding claw) can be changed to the open state by the operation tool provided on the handle pole.
Thus, a straight tube type fluorescent lamp mounting / dismounting / replacement device that can securely attach or remove the fluorescent lamp with a simple operation is configured.
Other features will become more apparent in the detailed description of the preferred embodiment.
A straight tube type fluorescent lamp mounting / dismounting / replacement apparatus according to the present invention includes a long linear handle pole, a cross beam frame having a substantially C-shaped cross section extending in an orthogonal direction on the upper side of the handle pole, and Two base brackets facing each other in the width direction of the cross beam frame are used as a base.
The handle pole is formed of a round metal pipe such as stainless steel. The handle pole is disposed substantially at the center in the longitudinal direction of the cross beam frame.
The cross beam frame has substantially the same width as the diameter of the glass tube, and is formed of C-shaped steel such as stainless steel whose lower surface is opened along the longitudinal direction. The cross beam frame is formed with a length shorter than the length of the fluorescent lamp in order to reduce the weight of the entire tool.
The base bracket is a substantially inverted trapezoidal plate member projecting downward from substantially the center of the cross beam frame, and is attached to the cross beam frame by fixing the wide upper side to the front and rear surfaces of the cross beam frame.
The horizontal girder frame is provided with the following chuck and movable frame.
Two chucks are provided for holding or releasing the glass tube of the fluorescent lamp, and two chucks are provided at substantially equal intervals in the longitudinal direction from the center position of the cross beam frame. Each chuck is assembled with a pair of clamping claws facing each other in the width direction of the cross beam frame. The pair of clamping claws are attached so that they can be opened and closed from the upper side of the claws by attracting and supporting them with a tension spring in a normally closed state. The tension spring is stretched below the middle side of each clamping claw across the width direction of the cross beam frame.
Each chuck is assembled with a lock that cuts between the tension springs relative to the position where the tension spring is passed to change each clamping claw from a closed state to an open state.
The lock is longer than the horizontal girder frame and is formed in a substantially quadrangular frame shape that encloses the entire girder in the width direction. In the closed state of the holding claws, the lock is spaced between the lower side and the lower surface of the cross frame. When the lock is pushed up until the lower side comes into contact with the lower surface of the cross beam frame, the lock holds the holding claws in an open state by interrupting between the relative positions of the holding claws above the position where the tension spring is stretched. On the other hand, the holding claws can be returned to the closed state by being pushed down from the upper side with a glass tube received between the holding claws in the opened state and removed from between the holding claws.
The movable frame is formed of a metal round pipe. The movable frame is housed inside the cross beam frame so that one end portion thereof is exposed to the outside of the cross frame end of the cross beam frame and is moved outwardly in the extending direction from the cross frame end of the cross beam frame. Further, a spring provided on the axis of the movable frame is supported in the retreating direction in the girder inside the horizontal girder frame.
A pusher tool is attached to the exposed side of the movable frame. The pusher device is attached so as to be relatively displaceable near the base of the fluorescent lamp, and is attached so as to be in contact with the socket case on one side. The two pusher tools are assembled in a pair of side inverted J-shaped frames that face each other in the width direction of the cross beam frame and present a side circular space larger than the diameter of the glass tube on the upper side. A pair of inverted J-shaped frames are attached from the upper side so that they can be opened and closed by bearing mounting on a front-facing U-shaped standing bracket. The standing bracket is attached to the movable frame.
Near the end of the movable frame from the position where the pusher is provided, there is provided a positioning set that determines the protruding direction of the terminal pin and the protruding length of the terminal pin with reference to the outer end side of the pusher.
The positioning set is formed by bending a thin metal wire. The positioning set has two support shaft portions that are parallel to each other in a vertical direction, and is bent toward the inner side in the width direction of the cross beam frame from the shaft lower end of the support shaft portion, and further, is a flat L-shape that bends outward. A base shaft portion and a side-downward U-shaped abutting shaft portion that rises above the outer shaft end of the base shaft portion are formed. The abutting shaft portion is provided such that the upper side of the shaft determines the protruding direction and the protruding length of the terminal pin.
The positioning set tool is attached to a standing bracket of the pusher tool. In the standing bracket, a pair of cylindrical portions are provided by curving both sides of the bracket plate located on the end side of the movable frame. The positioning set is held so as to be slidable up and down by inserting each support shaft portion through the cylindrical portion of the standing bracket.
When the fluorescent lamp is set on the upper side of the cross beam frame, the positioning set is slid upward until the bent portion of the base shaft portion continuous from the support shaft portion comes into contact with the cylindrical lower end of the standing bracket. . In the positioning set tool, two terminal pins are placed parallel to the upper axis side of the abutting shaft portion, and the end surface of the base is brought into contact with the upper axis side of the abutting shaft portion, thereby allowing the terminal pin to protrude and The protruding length of the terminal pin with reference to the outer end side of the pusher tool (the side in contact with the socket case) can be determined. If the protruding direction or length of the terminal pin varies with the glass tube held by the chuck and the fluorescent lamp set on the upper side of the cross beam frame, the terminal pin should be inserted into the socket terminal hole. Not happening.
After positioning the terminal pin, the positioning set can be retracted so as not to obstruct the terminal pin when it is inserted into the terminal hole of the socket by sliding downward on the cylindrical portion of the standing bracket.
The pole for the handle is inserted at the upper end side of the pole into the cross beam frame from between the base brackets. The pole for the handle is mounted on the plate surface of the base bracket by a pivot pin in which a pole portion to be inserted between the base brackets is spanned and fixed between lower plates of the base bracket.
The inner end side of the movable frame is axially connected by a connecting pin to the pole portion of the handle pole that is inserted into the beam of the cross beam frame. On the upper end side of the handle pole, there are provided slits facing each other by vertically cutting out both sides of the pole. The movable frame is axially connected so that the inner end side is inserted into the slit of the handle pole and extends in a direction perpendicular to the pole of the handle by a connecting pin that spans and fixes to the pole portion of the handle pole.
The handle pole can be swung by an operator toward a longitudinal direction of the cross-girder frame with a pivot pin fixed around the plate surface of the base bracket as a fulcrum. In accordance with the swinging operation of the handle pole, the movable frame protrudes from the one end of the cross beam frame outward in the extending direction by a predetermined length. The projecting amount of the movable frame is set so as to correspond to the stroke in which the socket is displaced in the socket case and the terminal pin comes out of the terminal hole of the socket.
Each lock is provided with a push-up lever that moves the pair of clamping claws to change from a closed state to an open state. The push-up lever is assembled from two lever arms corresponding to each lock and one pull-down rod that holds both lever arms. The lever arm and the pulling bar are formed by bending a thin metal wire.
Each lever arm is provided so that the base end side of the arm is positioned near the slit of the handle pole between the base brackets, and the front end side of the arm is extended just below the lock. Each lever arm is formed by bending it into an elongated rectangular shape. The distal end side of the arm is formed by being bent into a substantially V-shaped front surface that is continuous from the proximal side of the arm. Each lever arm has a V-shaped bent base disposed in the beam from the lower side of the cross beam frame, and is engaged with an axis of a support pin that is spanned and fixed in the width direction of the cross beam frame. The entire arm is attached so as to be swingable up and down with the support pin as a fulcrum.
The lowering rod is formed of a base shaft portion that has a vertically long and narrow U shape and a projecting shaft portion that is bent outward from each upper end side of the base shaft portion. The pulling rod is assembled so that the base shaft portion is inserted into the diameter of the handle pole, and the distal end side of the overhang shaft portion extends outside the slit of the handle pole. The tip end of the overhang shaft is formed as a substantially elliptical ring bending part, and the arm base end of each lever arm is loosely fitted and held loosely by the ring bending part, so that the pull down rod is integrated with each lever arm. It is assembled.
An operating ring for pulling down the push-up lever is provided on the handle side of the handle pole. The operation ring is fitted in the outer periphery of the handle pole and is formed in a vertically long cylindrical shape that can slide up and down. In addition, the vertical hole is provided opposite to both sides of the pole for the handle, and the support pin inserted through the vertical hole is fixed on both sides of the operation ring so that it can be slid and guided by the vertical hole and support pin. It is provided. The operation ring is connected to the push-up lever by a pulling strip such as a metal wire or a narrow metal tape connected between the support pin and the pulling rod.
When the pair of clamping claws are in the closed state holding the glass tube, that is, when the lock is in a state of being released from between the clamping claws, when the push lever is pulled with the operation ring, each lever arm swings upward, By pushing up the lock with each lever arm and inserting it between the clamping claws, the clamping claws can be changed from the closed state to the opened state.

　図示の実施例に係る直管型蛍光灯の着脱交換器具（以下、「本実施例」という。）は、図１で示すと同じ直管型蛍光灯を天井等の高所に設置された蛍光灯の設置設備より着脱交換するに用いられる。
　本実施例は、図２，図３で示すように長尺な直線状の取手用ポール１と、取手用ポール１の上部側で直交方向に亘る横桁フレーム２と、更に、横桁フレーム２の幅方向で相対する二枚の基体ブラケット３（正面側のみ図示）をベースに構成されている。
　取手用ポール１は、非導電処理が施されたステンレス等の金属製丸パイプで形成されている。取手用ポール１は、横桁フレーム２，基体ブラケット３を上ポール部１ａに組み付ける便宜上、上ポール部１ａと下ポール部１ｂが別体に形成されている。上ポール部１ａ，下ポール部１ｂは継ぎ管１ｃを両者の径内に嵌装し、ビス１ｄ，１ｅを上ポール部１ａ，下ポール部１ｂの外面側より継ぎ管１ｃに螺着することにより一本棒として組み立てられている。
　横桁フレーム２は、ガラス管の径と略同じ幅を有し、下部面を長手方向に沿って開放したステンレス等のＣ字鋼で形成されている。横桁フレーム２は、具全体を軽量化するべく、蛍光灯の長さよりも短い長さに形成されている。横桁フレーム２の上部面には、ガラス管との当接を緩衝する弾性カバー２ａが長手方向に亘って被着されている。
　基体ブラケット３は横桁フレーム２の略中央から下方に張り出す略逆台形の板部材でなり、広幅な上辺側を横桁フレーム２の前面，後面にあてがい固定させて横桁フレーム２に取り付けられている。
　取手用ポール１は、ポール上端側が基体ブラケット３の間から横桁フレーム２の桁内に挿置されている。
　取手用ポール１は、枢軸ピン４をポール上端側に挿通させて基体ブラケット３の各下部寄り板間に掛渡し固定することにより枢軸ピン４で基体ブラケット３の各板面に軸承装着されている。取手用ポール１は、枢軸ピン４を支点に、後述する可動フレームの迫出し方向に相応する横桁フレーム２の長手方向片側に向けて揺動操作可能に取り付けられている。
　横桁フレーム２には、次のようなチャック具５ａ，５ｂ、可動フレーム６が設けられている。
　チャック具５ａ，５ｂは、蛍光灯のガラス管を抱込み保持乃至は解放するもので、横桁フレーム２の中央位置より略等間隔を長手方向に隔て二つ設けられている。各チャック具５ａ，５ｂ（以下、「チャック具５ａ」に基づいて説明する。）は、図４ａ，４ｂで示すように横桁フレーム２の幅方向で相向き合う一対の挟持爪５０，５１で組み立てられている。一対の挟持爪５０，５１は、爪上端側を引張りバネ５２ａ，５２ｂで閉じ方向に引合い支持することにより、爪上端側から開き，閉じ可能に取り付けられている。引張りバネ５２ａ，５２ｂは、横桁フレーム２の幅方向に亘って各挟持爪５０，５１の爪中腹より下寄りに掛渡し装着されている。
　挟持爪５０，５１は、三つに先割りされた半円弧状の爪先部５０ａ，５１ａと、爪先部５０ａ，５０ｂより下方に連続する平板状の基板部５０ｂ，５１ｂと、基板部５０ｂ，５１ｂの下端側より挟持爪５０，５１の相対方向に折れ曲る二つの支点片部５０ｃ，５０ｄ、５１ｃ（一つ図示せず）と、爪先部５０ａ，５１ａと基板部５０ｂ，５１ｂとの間の略中腹辺より相対方向に突出する略横向きＶ字状の抉上げ部５０ｅ，５１ｅを備えて形成されている。
　爪先部５０ａ、５１ａは、上端側を相対方向に弯曲させてガラス管を抱込み保持可能に形成されている。爪先部５０ａ、５１ａには、ガラス管との当接を緩衝する弾性カバー５０ｆ，５１ｆが相対面に被着されている。支点片部５０ｃ，５０ｄ、５１ｃは、横桁フレーム２の前面，後面に設けた二つの係合穴２ｂ，２ｃ、２ｄ（一つ図示せず）と挿置されている。係合穴２ｂ，２ｃ、２ｄは、後述するロックを両側よりスライド案内するよう横桁フレーム２に嵌込み固定された側面上向きコの字状のガイド板７ａ，７ｂの板面より横桁フレーム２の前面，後面に連続するよう設けられている。挟持爪５０，５１は、各係合穴２ｂ，２ｃ、２ｄに挿置された支点片部５０ｃ，５０ｄ、５１ｃを支点に、爪上端側から開き乃至は閉じ可能に引張りバネ５２ａ，５２ｂで横桁フレーム２に組み付けられている。
　引張りバネ５２ａ，５２ｂはコイルスプリングでなり、後述するロック８ａ，８ｂ（図３参照）を介して両側に配置されている。各引張りバネ５２ａ，５２ｂは、バネ本体を横桁フレーム２の桁内幅方向に配置し、バネ端を横桁フレーム２の前面，後面に設けた抜き穴（符号なし）より外方に引き出すと共に、基板部５０ｂ，５１ｂの板面に設けた切起し片５０ｇ，５０ｈ、５１ｇ（一つ図示せず）に掛け止めて抉上げ部５０ｅ，５１ｅの下寄りで横桁フレーム２の幅方向に亘るよう掛け渡されている。
　各チャック具３ａ，３ｂには、引張りバネ５２ａ，５２ｂの掛渡し位置より上方の相対間に割り込んで一対の挟持爪５０，５１を閉じ状態より開き状態に変えるロック８ａ，８ｂが組み付けられている。
　ロック８ａ，８ｂ（以下、「ロック８ａ」に基づいて説明する。）は、図５ａで示すように桁全体を幅方向で囲込み可能な下部辺８０、前後部辺８１，８２、上部辺８３から略四辺形の枠状に形成されている。上部辺８３には、ガラス管との当接を緩衝する弾性カバー８４が被着されている。
　ロック８ａは、挟持爪５０，５１の閉じ状態では、下部辺８０と横桁フレーム２の下部面との間に間隔Ｇを保てるよう横桁フレーム２より縦長に形成されている（図４ａ，図４ｂ参照）。ロック８ａは、図５ｂで示すように下部辺８０が横桁フレーム２の下部面と当たるまで上方に押し上げると、前後部辺８１，８２が引張りバネ５２ａ，５２ｂの掛渡し位置より上方で挟持爪５０，５１の抉上げ部５０ｅ，５１ｅに当る。この抉上げ部５０ｅ，５１ｅでの離間により、挟持爪５０，５１は開き状態に保つ。一方、開き状態にある各挟持爪５０，５１の間に受け入れるガラス管によりロック８ａを上部辺８３から押し下げると、抉上げ部５０ｅ，５１ｅより外れて横桁フレーム２の上部面まで下がり、挟持爪５０，５１は閉じ状態に戻る。
　可動フレーム６は、金属製の丸パイプで形成されている。可動フレーム６（図３参照）は、片端部を横桁フレーム２の桁片端より外側に露出し、横桁フレーム２の桁片端から延長方向外方に迫出し可能に横桁フレーム２の内部に収容されている。また、横桁フレーム２の内部で可動フレーム６の軸線上に備えるコイルスプリング９により、横桁フレーム２の桁内で退却方向にバネ引張されている。
　可動フレーム６の露出する端部側には、図６ａ，図６ｂで示すようにプッシャ具１０が取り付けられている。プッシャ具１０は、蛍光灯の口金付近を相対的にズレ動き可能に受け入れ、また、ソケットケースの前面側と外端辺で当接可能に取り付けられている。
　プッシャ具１０は、二つが横桁フレーム２の幅方向で向き合い、上部側がガラス管の径より大きな側面円形の空間を呈する一対の側面逆Ｊ字枠１００，１０１で組み立てられている。各Ｊ字枠１００，１０１は、正面上向きコの字状の立付けブラケット１０２に軸承装着することにより上部側から開き，閉じ可能に取り付けられている。立付けブラケット１０２は、コの字の底部辺を可動フレーム６の下部側にあてがってビス１０３で締付け固定することにより可動フレーム６に取り付けられている。
　各Ｊ字枠１００，１０１は、略中腹辺の両側縁より横桁フレーム２の幅方向に突出する張出しブラケット１００ａ，１００ｂ、１０１ａ，１０１ｂを有する。各Ｊ字枠１００，１０１は、立付けブラケット１０２の板面間に掛渡し固定する支軸ピン１００ｃ、１０１ｃを張出しブラケット１００ａ，１００ｂ、１０１ａ，１０１ｂに挿通することにより、立付けブラケット１０２の板面に軸承装着されている。張出しブラケット１００ａ，１００ｂ，１０１ａ，１０１ｂの突端（内端）側には、ゴム弾性を有する溝付きリング１００ｄ，１０１ｄが支軸ピン１００ｅ，１０１ｅで掛渡し固定されている。各Ｊ字枠１００，１０１は、下部側１００ｆ，１０１ｆを可動フレーム６と当接するまで伸ばし、引張りバネ１０４を張出しブラケット１００ａ，１００ｂ、１０１ａ，１０１ｂの略直下で下部側１００ｆ，１０１ｆに掛け渡すことにより、湾曲形状の上部側１００ｇ，１０１ｇから開放可能に取り付けられている。
　プッシャ具１０を備える位置より可動フレーム６の端部寄りには、端子ピンの突出向き並びにプッシャ具１０の外端辺よりの突出長さを定める位置決めセット具１１が設けられている。
　位置決めセット具１１は、金属細線を折り曲げて形成されている。位置決めセット具１１は、縦で相平行する二本の支軸部１１０，１１１と、支軸部１１０，１１１の軸下端より横桁フレーム２の幅方向内側に向けて折れ曲がり、更に外方に向けて折れ曲がる平面Ｌ字状の基軸部１１２，１１３と、基軸部１１２，１１３の軸端より上方に立ち上がる側面下向きコの字状の付当て軸部１１４から形成されている。付当て軸部１１４は、上辺軸が端子ピンの突出向き並びに突出長さを定めるものとして設けられている。付当て軸部１１４には、ゴム弾性を有する溝付きリング１１５が上辺軸の軸線上に嵌装させて備え付けられている。
　位置決めセット具１１は、プッシャ具１０の立付けブラケット１０２に取り付けられている。立付けブラケット１０２には、二つの円筒部１０２ａ，１０２ｂが可動フレーム６の端部側に位置するブラケット板の両側辺を湾曲させて設けられている。位置決めセット具１１は、各支軸部１１０，１１１を立付けブラケット１０２の円筒部１０２ａ，１０２ｂに挿通させて上下にスライド可能に保持されている。
　プッシャ具１０が外端辺でソケットケースの前面側と当接した状態では、立付けブラケット１０２の円筒部１０２ａ，１０２ｂはソケットケースの両側部に、位置決めセット具１１の付当て軸部１１４はソケットケースの下部側に相応位置するよう組み付けられている。立付けブラケット１０２は、上部辺１０２ｃ，１０２ｄが口金と当接しないよう各ブラケット板の上寄り板面を半円状に刳り抜いて形成されている。
　位置決めセット具１１は、蛍光灯を横桁フレーム２の上部側にセットする際、支軸部１１０，１１１より連続する基軸部１１２，１１３の屈曲部が立付けブラケット１０２の円筒下端と当接するまで支軸部１１０，１１１で上方にスライド位置する。位置決めセット具１１は、二本の端子ピンを付当て軸部１１４の溝付きリング１１５に平行に載せると共に、口金の端面を付当て軸部１１４の溝付きリング１１５と当接させられるよう備え付けられている。これにより、端子ピンの突出向き並びにプッシャ具１０の外端辺（ソケットケースとの当接側）を基準にとした端子ピンの突出長さが定められる。
　端子ピンの位置決め後は、位置決めセット具１１は具全体を立付けブラケット１０２の円筒部１０２ａ，１０２ｂで下方にスライドすれば、端子ピンをソケットの端子穴に差し込む際の邪魔とならないよう退却させられる。
　取手用ポール１は、ポール上端側が基体ブラケット３の間から横桁フレーム２の桁内に挿置されている。取手用ポール１は、基体ブラケット３の間に挿置するポール部分が基体ブラケット３の下部寄り板間に掛渡し固定する枢軸ピン４で基体ブラケット３の板面に軸承装着されている。
　横桁フレーム２の桁内に挿置する取手用ポール１のポール部分には、可動フレーム６の内端側が連結ピン１ｆで軸承連結されている（図３参照）。取手用ポール１の上端側には、図７で示すようにポール両側面を縦に切り抜いてスリット１ｇが相対するよう設けられている。可動フレーム６は、内端側が取手用ポール１のスリット１ｇに挿置されている。その可動フレーム６の内端側は、取手用ポール１のポール部分に掛渡し固定する連結ピン１ｆで軸承連結されている。
　取手用ポール１は、枢軸ピン４（図３参照）を支点に、作業員が可動フレーム６の迫出し方向に相応する横桁フレーム２の長手方向片方に向けて揺動操作するよう備えられている。この取手用ポール１を片方に揺動操作するだけで、可動フレーム６を横桁フレーム２の片端部から外方の延長方向に所定の長さ分だけ迫り出せるようにできる。可動フレーム６の迫出し量は、ソケットがソケットケースの内部で没入変位すると共に、端子ピンを端子穴より抜き出るストロークと相応するよう設定されている。
　ロック８ａ，８ｂには、押上げレバー１２が設けられている（図３参照）。押上げレバー１２は、一対の挟持爪５０，５１がガラス管を抱え込んだ状態、即ち、ロック８ａ，８ｂが挟持爪５０，５１の間より外れた状態にあるとき、ロック８ａ，８ｂを挟持爪５０，５１の間に割り込ませて挟持爪５０，５１を閉じ状態から開き状態に変えるものとして設けられている。
　押上げレバー１２は、図８ａ，図８ｂで示すように各ロック８ａ，８ｂに対応する二つのレバーアーム１２０，１２１と、各レバーアーム１２０，１２１を保持する一つの引下げ杆１２２から組み立てられている。各レバーアーム１２０，１２１、引下げ杆１２２は金属細線を折り曲げて形成されている。
　各レバーアーム１２０，１２１は、アーム基端側１２０ａ，１２１ａを基体ブラケット３の間で取手用ポール１のスリット寄りに位置し、アーム先端側１２０ｂ，１２１ｂをロック８ａ，８ｂの直下に伸ばすよう備え付けられている（図３参照）。各レバーアーム１２０，１２１は、金属細線を平面細長な四辺形に折り曲げて形成されている。アーム先端側１２０ｂ，１２１ｂは、アーム基部側１２０ａ，１２１ａより連続する正面略Ｖ字状を呈するよう形成されている。各レバーアーム１２０，１２１は、Ｖ字の屈曲基部１２０ｃ，１２１ｃを横桁フレームの開放された下部側より桁内に挿置すると共に、横桁フレーム２の幅方向に掛渡し固定した支持ピン１ｈ，１ｉの軸線上に係合することにより、アーム全体が支持ピン１ｈ，１ｉを支点に上下に揺動可能に取り付けられている。アーム先端側１２０ｂ，１２１ｂには、ロック８ａ，８ｂを押し上げる当接リング１２０ｄ，１２１ｄが軸線上に嵌装させて備え付けられている。
　引下げ杆１２２は、狭幅縦長な正面上向きのコの字を呈する基軸部１２２ａと、コの字の各上端側より略直角方向外方に折れ曲がる張出し軸部１２２ｂ，１２２ｃとから形成されている。引下げ杆１２２は、基軸部１２２ａを取手用ポール１の径内に挿置し、張出し軸部１２２ｂ，１２２ｃの先端側を取手用ポール１のスリット１ｆより径外に伸ばすことにより取手用ポール１に組み付けられている（図３参照）。張出し部１２２ｂ，１２２ｃの先端側は、略楕円形の輪曲げ部１２２ｄ，１２２ｅとして形成されている。引下げ杆１２２の張出し軸部１２２ｂ，１２２ｃは、各アーム基端側１２２ｂ，１２２ｃを輪曲げ部１２２ｄ，１２２ｅでズレ動き可能に遊嵌保持することにより、各レバーアーム１２０，１２１と連結されている。
　取手用ポール１の握り手側（図２参照）には、押上げレバー１２を引張り下げる操作環１３が設けられている。操作環１３は、取手用ポール１の外周に嵌め合わされて上下にスライド可能な縦長な円筒状に形成されている。また、縦長穴（図示せず）を取手用ポール１の相対する両側面に設けると共に、縦長穴に挿通する支軸ピン１４を操作環１３の両側面に掛渡し固定することにより縦長穴，支軸ピン１４でスライド案内可能に取り付けられている。操作環１３は、支軸ピン１４と引下げ杆１２２の間に連結する金属ワイヤ，幅狭な金属テープ等の牽引条１５でロックの押上げレバー１２と繋がれている。
　このように構成する直管型蛍光灯の着脱交換器具を用いては、既設の蛍光灯を取り外す場合、まず、作業員がロック８ａ，８ｂを挟持爪５０，５１の相対間に割り込ませるよう押し上げて挟持爪５０，５１の爪上端側を開き状態に保つ（図５ｂ参照）。位置決めセット具１１は、図９で示すように具全体を立付けブラケット１０２の円筒部１０２ａ，１０２ｂでスライド降下させて退却させて置くとよい。プッシャ具１０は、一対のＪ状枠１００，１０１が上向きの開き状態にコイルスプリング１０４で保たれている（図６ａ参照）。
　次に、図１０で示すように作業者が具全体を取手ポール１で蛍光灯の設置場所まで持ち上げ、まず、プッシャ具１０の上端側１００ｇ，１０１ｇをソケットケースＳ１の前面側に当ててプッシャ具１０を位置決めする。このソケットケースＳ１の前面側を規制面とし、具全体をガラス管Ｇと平行させるまで取手用ポール１で押し上げる。
　具全体をガラス管Ｇと平行になるまで押し上げると、図１１ａで示すようにチャック具８ａ，８ｂがガラス管Ｇを各開いた挟持爪５０，５１の間に受け入れる。それに伴って、ロック８ａ，８ｂが挟持爪５０，５１の間に受け入れたガラス管Ｇで押し下げられて挟持爪５０，５１の間から外れる。そのロック８ａ，８ｂの外れにより、図１１ｂで示すように一対の挟持爪５０，５１が閉じてガラス管Ｇをチャック具５ａ，５ｂで抱込み保持する。
　プッシャ具１０は、図１２ａで示すように口金Ｃ１をＪ字枠１００，１０１の開いた上部側より内側に受け入れ、溝付きリング１００ｄ，１０１ｄが口金Ｃ１で押し下げられることから、図１２ｂで示すようにＪ字枠１００，１０１が閉じる。
　このＪ字枠１００，１０１の閉じにより、図１３で示すようにプッシャ具１０の上部側１００ｇ，１０１ｇが口金付近をガラス管の同芯円上で非接触状態に囲い込み、プッシャ具１０の外端辺がソケットケースＳ１の前面側と相対状態になる。
　ガラス管Ｇをチャック具５ａ，５ｂで抱込み保持し、口金付近をプッシャ具１０で取り囲んだならば、図１４ａで示すよう作業者が取手用ポール１の握り手側をプッシャ具１０の取付け側と反対方向（紙面右側）に揺動操作する。この取手用ポール１の揺動操作により、枢軸ピン４を支点に、横桁フレーム２の桁内に挿置した取手用ポール１のポール部分が取手用ポール１の操作方向と反対方向に揺動し、可動フレーム６が横桁フレーム２の桁片端より延長方向外方に迫り出す。それに伴って、プッシャ具１０が当該側のソケットケースＳ１を押圧する。
　プッシャ具１０がソケットケースＳ１を押圧すると、図１４ｂで示すように灯全体を含む具全体（図示省略）がプッシャ具１０と相対的にズレ動き、灯全体により、反対側のソケットＳ２をソケットケースＮ２の内部にバネ変位で没入させる。一方で、プッシャ具１０で押圧しているソケット側の端子ピンＰ１がソケットＳ１の端子穴から抜け出る。
　プッシャ側の端子ピンＰ１がソケットＳ１の端子穴より抜け出た状態から、図１５ａで示すように取手用ポール１を揺動状態に保ったまま、具全体を取手用ポール１でやや斜めの姿勢にし、プッシャ側と反対側のソケットＳ２をソケットケースＮ２の内側でバネ変位により斜めに没入させる。
　その具全体を斜め姿勢にすると共に、ソケットＳ２の没入状態を保ち、取手用ポール１の操作により具全体を斜め姿勢にしたままプッシャ具１０をソケットケースＮ１から引き下げる。このプッシャ具１０の引下げにより、図１５ｂで示すようにソケット側の端子ピンＰ１がソケットケースＮ１より下方に外れる。また、取手用ポール１を元に戻しながら、プッシャ具１０を当該側のソケットケースＳ１から外し出す。
　プッシャ具１０がソケットケースＳ１より外れると、作業員の取手用ポール１による具全体の横ズラし操作により、プッシャ側と反対側の端子ピンＰ２もソケットＳ２の端子穴から外し出せる。
　このような手順により、ガラス管をチャック具５ａ，５ｂで抱込み保持したまま具全体を取手用ポール１で下ろせば、蛍光灯を作業員の手元まで持ち運べる。更に、作業員が各挟持爪５０，５１を手元で開くことにより、蛍光灯をチャック具５ａ，５ｂから取り外せる。
　新規な蛍光灯の取付けにあたっては、まず、作業者がチャック具５ａ，５ｂをロック８ａ，８ｂで開き状態に保つ（図５ｂ参照）。次に、蛍光灯を横桁フレーム２の上に位置決めセットするに、図１６で示すように片方の口金Ｃ１を端子ピンＰ１の突出する端面で位置決めセット具１１の溝付きリング１１５に当接させ、端子ピンＰ１を溝付きリング１１５の上に載せる。これにより、端子ピンＰ１がソケットＮ１の端子穴と整合するよう二本平行向きに並び、プッシャ具１０の外端辺より端子ピンＰ１の突出長さが決められる。
　端子ピンＰ１を位置決めしたならば、作業員がロック８ａ，８ｂをガラス管Ｇの押し付けによる押し下げて挟持爪５０，５１の間より外し、ガラス管Ｇをチャック具５ａ，５ｂで枹込み保持させる。また、プッシャ具１０が口金付近をガラス管の同芯円上で非接触状態に囲い込むことにより、図１７で示すように灯全体を横桁フレーム２の上部面に位置決めセットさせる。
　蛍光灯のセット後、作業員が灯全体を含む具全体を取手用ポール１で蛍光灯の取付け場所まで持ち上げ、具全体を取手用ポール１でやや斜めに保ち、まず、プッシャ具１０と反対側の端子ピンＰ２をソケットＳ２の端子穴と位置合わせて差し込む。
　この後に、作業員が灯全体を含む具全体を取手用ポール１で端子ピンＰ２の差込み側にズラし動かすことから、図１８で示すように当該側のソケットＳ２をソケットケースＮ２の内部に斜めに没入変位させる。次に、作業員が端子ピンＰ２を差し込んだソケットＳ２を灯全体で斜めに没入変位させるよう保ち、ソケットＳ２を取手用ポール１の操作で押しながら、プッシャ具１０の上部側をソケットケースＮ１の前面側に当接させてズラし上げ、プッシャ側の端子ピンＰ１をソケットケースＮ１の下部近くに接近させる。
　その後に、作業者が上述した如く取手用ポール１を揺動操作することにより、可動フレーム６を伸び出させると共に、具全体を水平状態にするようプッシャ具１０の外端辺をソケットケースＮ１の前面側に合わせてプッシャ具１０を全体的に押し当てる。
　このプッシャ具１０の押当てにより、灯全体を含む具全体をプッシャ具１０と相対的にズレ動かせるから、プッシャ具１０と反対側のソケットＳ２を灯全体で完全に没入変位させる。一方で、プッシャ側の端子ピンＰ１をソケットＳ１の端子穴と位置合わせできる（図１４ａ，図１４ｂ参照）。
　プッシャ側の端子ピンＰ１をソケットＳ１の端子穴に位置合せしたならば、作業者が取手用ポール１を元に戻すと、可動フレーム６が横桁フレームの桁内に退却し、灯全体を含む具全体が可動フレーム６の退却により相対的にズレ動く。この具全体のズレ動きにより、プッシャ具１０と反対側のソケットＳ２が迫出し変位すると同時に、プッシャ側の端子ピンＰ１をソケットＳ１の端子穴に差し込めることにより、蛍光灯をソケットＳ１，Ｓ２の間に掛渡し装着できる（図１３参照）。
　蛍光灯の取付け後、作業員が操作環１３を取手用ポール１の下方にスライド移動すると、押上げレバー１２の引下げ杆１２２が牽引条１５で引き下げられると共に、レバーアーム１２０，１２１が支点ピン１ｈ，１ｇにより上方に揺動する。このレバーアーム１２０，１２１の揺動は、各アーム基端側１２２ｂ，１２２ｃと輪曲げ部１２２ｄ，１２２ｅのズレ動きで許容される。
　そのレバーアーム１２０，１２１の揺動により、図１９で示すようにレバーアーム１２０，１２１がロック８ａ，８ｂを押し上げて挟持爪５０，５１の間に割り込ませる。挟持爪５０，５１はロック８ａ，８ｂの割込みにより開き状態に変るから、チャック具５ａ，５ｂをガラス管Ｇより外出し取れる。
　その蛍光灯の取付け，取外しのいずれに際しても、チャック具５ａ，５ｂがガラス管と擦れることがない。また、プッシャ具１０は取手用ポール１による具全体の取外しに伴ってコイルスプリング１０４で開くため、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。
　上述した実施例では、金属細線を折り曲げて形成した位置決めセット具１１を備えたが、図２０ａで示すように縦長な短冊片１１を位置決めセット具として備えるようにできる。短冊片１１’は、不要時に水平方向に倒し逃がせるよう、立上り基部を可動フレーム６の端部面にあてがってビス１１ａ’で回転可能に取り付けられている。上部辺の両端部１１ｂ’，１１ｃ’は、短冊片１１’の回転に伴って端子ピンＰ１と当たらないよう円弧状に角取りされている。
　その短冊片１１’によっても、蛍光灯を横桁フレーム２の上に位置決めセットするに、図２０ｂで示すように片方の口金Ｃ１を端子ピンＰ１の突出する端面で位短冊片１１’の板面に当接させ、端子ピンＰ１を短冊片１１’の上部辺１１ｄ’に載せることにより、端子ピンＰ１をソケットＮ１の端子穴と整合するよう二本平行向きに並べ、プッシャ具１０の外端辺より端子ピンＰ１の突出長さを決められる。
