Description

【０００１】
【発明の属する技術分野】
本発明は、電球の口金を取り外す口金取外し装置に関する。
【０００２】
【従来の技術】
一般に、電球点灯時の発熱によって電球ガラス部と口金部の接着剤が熱劣化し、電球取外し時にガラス部のみが外れてソケット内に電球の口金が残ったり、作業者の不注意等で電球を破裂させてしまったりしたとき、新しい電球を取付けるためにこの口金を取り除く必要があった。
【０００３】
従来におけるこの取外し作業に用いる取外し装置は、実開昭６１−３８７６３号公報に記載されており、この一部断面図を図７に示している。
【０００４】
操作部１の先端側に、電球の口金内に嵌合する形に整形した弾性体２をビス３によって固定し、一方、操作部１の下部に嵌入孔部１ａを形成し、この嵌入孔部１ａ内に多段に伸縮自在な棒状体からなる操作補助具４を挿入した後、回り止めピン５を差し込んで操作補助具４の回転操作力を操作部１に確実に伝えるようにすると共に、締付けボルト６によって操作補助具４を操作部１に取り外し可能に連結している。このように構成した口金取外し装置は、図示しないソケット内に残っている口金に弾性体２を挿入して押し付けて弾性体２と口金とを一体にし、その後、操作部１を回転して弾性体２を介して口金を回転させて取り外すようにしていた。
【０００５】
【発明が解決しようとする課題】
しかしながら、従来の口金取外し装置は、口金に弾性体２を挿入して押し付けて弾性体２と口金とを一体にするために、弾性体２の挿入方向に力を加えて弾性体２をしっかりと口金内周面にねじ込まなければならず、そのねじ込みが不十分であると弾性体２と口金内周面との間に滑りが生じ、その取り外しができないという作業性の面での不都合があった。
【０００６】
本発明の目的は、容易に口金を取り外すことができるようにした口金取外し装置を提供することにある。
【０００７】
【課題を解決するための手段】
本発明は上記目的を達成するために、電球のソケットに残った口金を取り外す口金取外し装置において、上記口金の中に挿入する少なくとも一対の爪部と、この爪部に対して上記口金の内壁を外周方向へ圧接する力を付与するばね手段と、上記爪部に回転力を付与する回転手段とを備えたことを特徴とする。
【０００８】
本発明による口金取外し装置は、少なくとも一対の爪部をばね手段によって口金の内壁に外周方向への力を加えて圧接し、回転手段によって爪部に回転を加えて口金を回して外すようにしたため、従来のように口金取外し作業時に、ソケットに残った口金内へ挿入方向へ弾性体を強くねじ込む必要がないため、場所や高さ位置などの制約を受けることなく作業性良く容易に口金の取外し作業を行なうことができる。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【００１０】
図１および図２は、本発明の一実施の形態による口金取外し装置の要部を示す平面図および側面図である。
【００１１】
口金取外し装置１０は、後述する口金９の内壁と当接する爪部１１ａ，１２ａをそれぞれ先端部に有する略Ｕ字状の腕部１１，１２の中間部間にピン１３を連結し、このピン１３をばね１４の中心部内に挿入して、ばね１４によって爪部１１ａ，１２ａ間に互いに開離する方向の力を与えると共に、ピン１３によってばね１４の位置ずれを防止している。腕部１１，１２の爪部１１ａ，１２ａと反対側端部には、後述する回転手段３０と接続するための貫通穴１５ａを有する接続部１５があり、この接続部１５はリベット１６によって腕部１２の折り曲げ部に連結固定されている。
【００１２】
爪部１１ａ，１２ａは、拡大正面図である図３に示すように口金９内に効果的に圧接するように口金９より堅い材質で作成されている。また爪部１１ａ，１２ａの先端は鋭利に形成されており、この爪部１１ａ，１２ａがばね１４の力を受けて口金９の内壁に喰い込み、後述するように口金７の回転が可能となる。さらに、この口金９の内壁は凹凸が存在するため、爪部１１ａ，１２ａの軸方向長を互いに異なるように形成すると、確実に口金９の内壁の凹部に圧接させることができる。
【００１３】
ばね１４によって両腕部１１，１２には捻れが加わるが、一方の腕部１２の中間部には、一対のねじれ防止板１７ａ，１７ｂがボルトなどによって固定され、この一対のねじれ防止板１７ａ，１７ｂ間に他方の腕部１１を位置させることにより両腕部１１，１２の捻れを防止している。また同様の目的で、両腕部１１，１２の外側には補強用のリブ１８ａ，１８ｂをそれぞれ設け、両爪部１１ａ，１２ａの対向側には補強用の当て板１９ａ，１９ｂをそれぞれ設け、また両腕部１１，１２の折り曲げ部近傍にも補強用の当て金２０ａ，２０ｂをそれぞれ設けている。
【００１４】
両リブ１８ａ，１８ｂの同位置にはそれぞれ貫通穴２１が形成され、リブ１８ｂの貫通穴にはばね規制具２２の一端２２ａが挿入されている。この一端２２ａにはねじ部が形成されており、リブ１８ｂから導出したこのねじ部にナット２３を螺合して抜け止めしている。このばね規制具２２は、図４に示したように一端２２ａを他端２２ｂよりも長くして略Ｕ字状に構成しており、リブ１８ａの貫通孔２１にはばね規制具２２の他端２２ｂが挿入可能となっている。ばね１４に抗して両腕部１１，１２を互いに近接させた後、ばね規制具２２の他端２２ｂを貫通孔２１に挿入すると、両腕部１１，１２は同状態を保持する。このばね規制具２２の中間部にはロープ状部材２４が連結されており、このロープ状部材２４を引くことにより他端２２ｂを貫通孔２１から抜き出し、ばね１４によって両腕部１１，１２間が所定の開離状態になるようにしている。
【００１５】
次に、上述した口金取外し装置２０を用いて電球を破裂させてしまった口金９の除去作業について説明する。
【００１６】
先ず、図５に示すように口金取外し装置２０に回転手段３０を連結する。この回転手段３０は、作業者が把持する長尺体３４の上下部に第１の軸すなわち回転軸３７、第２の軸すなわち回転軸３８を可回転的に設け、これらの回転軸３７，３８に索状体３３によって連結した第１のプーリ３５、第２のプーリ３６をそれぞれ回転軸３７，３８と同軸に取り付けて構成している。回転軸３７は爪部１１ａ，１２ａ間の略中央位置を含む直線上に延設され、回転軸３８は回転軸３７と略平行に延設されている。回転軸３７の先端部には図１に示した口金取外し装置２０の接続部１５に連結する装着部３１を備えており、また長尺体３４には索状体３３の張力を調整できるように軸長を可変できる調整機構を構成しておくのが望ましい。口金取外し装置２０と回転手段３０の連結は、接続部１５に形成した貫通穴１５ａと、回転手段３０の装着部３１に形成したばね孔の位置を相対させ、長ねじ３２で螺着することにより行なっている。
【００１７】
このとき、口金取外し装置２０は、リブ１８ｂの貫通孔にばね規制具２２の一端２２ａを挿入し、その端部に形成したねじ部にナット２３を螺合する。次に、ばね１４に抗して腕部１１，１２間を接近する方向に縮めた状態にし、ばね規制具２２の他端２２ｂをリブ１８ａの貫通穴２１に挿入して腕部１１，１２の同状態を保持する。
【００１８】
この状態で、図５に示すように爪部１１ａ，１２ａをソケット２５に残った口金９の中に挿入した後、ロープ状部材２４を引くとばね規制具２２の他端２２ｂがリブ１８ａの貫通穴２１から抜け、ばね１４によって腕部１１，１２間が広がり、図３および図６に示すように爪部１１ａ，１２ａがばね１４によって口金９の内壁にしっかりと圧接される。貫通穴２１から他端２２ｂが抜けたばね規制具２２は、一端２２ａがナット２３によってリブ１８ｂに保持されているので口金取外し装置２０から脱落することはない。
【００１９】
その後、作業者は回転手段３０の長尺体３４を把持しながら、図６に示した回転手段３０の索状体３３を介してプーリ３５，３６を所定方向に回転すると、口金７の内壁を外周方向へ押圧しながら圧接した爪部１１ａ，１２ａを介して口金７を回転させてソケット２５から安全に取り外すことができる。
【００２０】
このとき爪部１１ａ，１２ａは、要部拡大図である図３に示すように口金９内に効果的に圧接すると共に、その先端を鋭利に形成しているため、この爪部１１ａ，１２ａがばね１４の力を受けて口金９の内壁に喰い込み、容易に口金７をソケット２５から回転して取り外すことが可能である。さらに、腕部１１，１２はリブ１８ａ，１８ｂによって補強され、爪部１１ａ，１２ａは当て板１９ａ，１９ｂによって補強され、また両腕部１１，１２間にねじれ防止板１７ａ，１７ｂを設けているため、口金９の内壁に圧接した爪部１１ａ，１２ａにばね１４の力や、回転手段３０からの回転力を加えても、それによって塑性変形することはない。この補強に関しては種々の構成を採用することができる。
【００２１】
上述したように口金取外し装置２０は、少なくとも一対の爪部１１ａ，１２ａをばね１４によって口金９の内壁に外周方向への力を加えてしっかりと圧接するようにしたため、従来のように口金取外し作業時に、ソケット２５に残った口金９内へ挿入方向へ弾性体を強くねじ込む必要がないため、場所や高さ位置などの制約を受けることなく作業性良く容易に口金９の取外し作業を行なうことができる。
【００２２】
尚、上述した実施の形態では、回転手段３０として作業者が手で長尺体３３を操作して爪部１１ａ，１２ａに回転力を与えるようにしたが、電動の回転手段を用いてもよい。また爪部１１ａ，１２ａに口金９の内面への押圧力を付与するばね１４は腕部１１，１２間に配置したが、これに限らず口金９の内面への押圧力を付与する構成のばね手段であればよい。
【００２３】
【発明の効果】
以上説明したように本発明の口金取外し装置は、少なくとも一対の爪部をばねによって口金の内壁に外周方向への力を加えて圧接し、回転手段によって爪部に回転を加えて口金を回して外すようにしたため、従来のように口金取外し作業時に、ソケットに残った口金内へ挿入方向へ弾性体を強くねじ込む必要がないため、場所や高さ位置などの制約を受けることなく作業性良く容易に口金の取外し作業を行なうことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a base removing device for removing a base of a light bulb.
[0002]
[Prior art]
Generally, the adhesive between the bulb glass and the base is thermally degraded due to the heat generated when the bulb is turned on.When the bulb is removed, only the glass is removed and the bulb cap remains in the socket. When exploded, it was necessary to remove the base to install a new bulb.
[0003]
A conventional detaching device used for the detaching operation is described in Japanese Utility Model Laid-Open Publication No. 61-38663, and a partial cross-sectional view thereof is shown in FIG.
[0004]
An elastic body 2 shaped so as to fit into the base of the electric bulb is fixed to the distal end side of the operation unit 1 with a screw 3, while a fitting hole 1 a is formed in a lower part of the operation unit 1, and the fitting hole 1 a is formed. After inserting the operation aid 4 composed of a multi-stage telescopic rod-shaped body into 1a, a detent pin 5 is inserted to surely transmit the rotational operation force of the operation aid 4 to the operation unit 1 and tighten. The operation aid 4 is detachably connected to the operation unit 1 by bolts 6. The thus configured base removing device inserts and presses the elastic body 2 into the base remaining in the socket (not shown) to integrate the elastic body 2 and the base, and then rotates the operating unit 1 to rotate the elastic body. The base was rotated through 2 to remove the base.
[0005]
[Problems to be solved by the invention]
However, in the conventional base removing device, in order to insert the elastic body 2 into the base and press it to integrate the elastic body 2 and the base, a force is applied in the insertion direction of the elastic body 2 to firmly hold the elastic body 2. It must be screwed into the inner peripheral surface of the base. If the screwing is insufficient, slippage occurs between the elastic body 2 and the inner peripheral surface of the base, and there is an inconvenience in terms of workability that the removal cannot be performed. .
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a base removing device capable of easily removing a base.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a base removing device for removing a base remaining in a socket of a light bulb, wherein at least one pair of claws to be inserted into the base and an inner wall of the base with respect to the claws. It is characterized by comprising spring means for applying a force for pressing in the outer peripheral direction and rotating means for applying a rotational force to the claw portion.
[0008]
In the base removing device according to the present invention, at least a pair of claws are pressed against the inner wall of the base by applying a force in the outer circumferential direction by a spring means, and the base is rotated by rotating means to rotate and remove the base. Since there is no need to strongly screw the elastic body in the insertion direction into the base remaining in the socket when removing the base as in the past, the base can be easily removed with good workability without being restricted by the location or height position. Work can be done.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
1 and 2 are a plan view and a side view showing a main part of a base removing device according to an embodiment of the present invention.
[0011]
The base removing device 10 connects a pin 13 between the intermediate parts of the substantially U-shaped arms 11 and 12 having claw parts 11a and 12a at their distal ends, which come into contact with an inner wall of the base 9 described later. Is inserted into the center of the spring 14, a force is applied between the claws 11 a and 12 a in the direction of separating from each other by the spring 14, and the pin 13 prevents the spring 14 from being displaced. At the end of the arms 11 and 12 opposite to the claws 11a and 12a, there is a connecting portion 15 having a through hole 15a for connecting to a rotating means 30 described later. It is connected and fixed to twelve bent portions.
[0012]
As shown in FIG. 3 which is an enlarged front view, the claw portions 11a and 12a are made of a material harder than the base 9 so as to be effectively pressed into the base 9. The tips of the claws 11a and 12a are sharply formed. The claws 11a and 12a receive the force of the spring 14 and bite into the inner wall of the base 9, so that the base 7 can be rotated as described later. . Further, since the inner wall of the base 9 has irregularities, if the claw portions 11a and 12a are formed so that the axial lengths thereof are different from each other, the claw portions 11a and 12a can be reliably brought into pressure contact with the concave portions of the inner wall of the base 9.
[0013]
Although the arms 14 and 12 are twisted by the spring 14, a pair of twist preventing plates 17a and 17b are fixed to the middle of one arm 12 by bolts or the like, and the pair of twist preventing plates 17a and 17b are fixed. By positioning the other arm 11 between 17b, twisting of both arms 11, 12 is prevented. For the same purpose, reinforcing ribs 18a and 18b are provided on the outer sides of the arms 11 and 12, respectively, and reinforcing plates 19a and 19b are provided on opposite sides of the claws 11a and 12a, respectively. Reinforcing pads 20a and 20b are provided near the bent portions of the arms 11 and 12, respectively.
[0014]
A through hole 21 is formed at the same position on both ribs 18a and 18b, and one end 22a of a spring restricting tool 22 is inserted into the through hole of the rib 18b. A threaded portion is formed at the one end 22a, and a nut 23 is screwed into the threaded portion derived from the rib 18b to prevent the nut 23 from coming off. As shown in FIG. 4, the spring restricting member 22 has one end 22a longer than the other end 22b and has a substantially U-shape. The other end of the spring restricting member 22 is provided in the through hole 21 of the rib 18a. 22b can be inserted. After the arms 11 and 12 are brought close to each other against the spring 14, when the other end 22b of the spring restricting tool 22 is inserted into the through hole 21, the arms 11 and 12 maintain the same state. A rope-shaped member 24 is connected to an intermediate portion of the spring restricting member 22. The other end 22 b is pulled out from the through hole 21 by pulling the rope-shaped member 24, and the spring 14 connects between the two arm portions 11 and 12. A predetermined open state is set.
[0015]
Next, an operation of removing the base 9 that has ruptured the bulb using the base removing device 20 will be described.
[0016]
First, the rotating means 30 is connected to the base removing device 20 as shown in FIG. This rotating means 30 rotatably provides a first axis, that is, a rotating shaft 37, and a second axis, that is, a rotating shaft 38, at upper and lower portions of a long body 34 that is gripped by an operator. A first pulley 35 and a second pulley 36 connected to each other by a cord 33 are mounted coaxially with rotating shafts 37 and 38, respectively. The rotation shaft 37 extends on a straight line including a substantially central position between the claw portions 11a and 12a, and the rotation shaft 38 extends substantially parallel to the rotation shaft 37. The distal end of the rotating shaft 37 is provided with a mounting portion 31 connected to the connecting portion 15 of the base removing device 20 shown in FIG. 1, and the elongated body 34 is capable of adjusting the tension of the cord 33. It is desirable to configure an adjustment mechanism capable of changing the shaft length. The connection between the base removing device 20 and the rotating means 30 is performed by making the positions of the through hole 15 a formed in the connection part 15 and the spring hole formed in the mounting part 31 of the rotating means 30 opposite to each other, and screwing with the long screw 32. I do.
[0017]
At this time, the base removing device 20 inserts one end 22a of the spring restricting tool 22 into the through hole of the rib 18b, and screws the nut 23 into a threaded portion formed at the end. Next, the arms 11 and 12 are contracted against the spring 14 in a direction in which the arms 11 and 12 approach each other, and the other end 22b of the spring restricting tool 22 is inserted into the through hole 21 of the rib 18a so that the arms 11 and 12 are closed. The same state is maintained.
[0018]
In this state, after the claws 11a and 12a are inserted into the base 9 remaining in the socket 25 as shown in FIG. 5, when the rope-shaped member 24 is pulled, the other end 22b of the spring restricting tool 22 passes through the rib 18a. 3 and 6, the claws 11a and 12a are firmly pressed against the inner wall of the base 9 by the spring 14. As shown in FIGS. The spring restricting tool 22 from which the other end 22b comes out of the through hole 21 does not fall off from the base removing device 20 because one end 22a is held by the rib 18b by the nut 23.
[0019]
Thereafter, the operator rotates the pulleys 35 and 36 in a predetermined direction via the cord-like body 33 of the rotating means 30 shown in FIG. The base 7 can be safely removed from the socket 25 by rotating the base 7 via the claw portions 11a and 12a pressed against the outer circumferential direction.
[0020]
At this time, the claws 11a and 12a are effectively pressed into the base 9 as shown in FIG. 3, which is an enlarged view of a main part, and the tips thereof are sharply formed. Under the force of the spring 14, it can bite into the inner wall of the base 9, and the base 7 can be easily rotated and removed from the socket 25. Further, the arms 11 and 12 are reinforced by ribs 18a and 18b, the claws 11a and 12a are reinforced by backing plates 19a and 19b, and twist prevention plates 17a and 17b are provided between the arms 11 and 12. Therefore, even if the force of the spring 14 or the rotating force from the rotating means 30 is applied to the claw portions 11a and 12a pressed against the inner wall of the base 9, it is not plastically deformed. Various configurations can be employed for this reinforcement.
[0021]
As described above, in the base removing device 20, since at least the pair of claws 11a and 12a are firmly pressed against the inner wall of the base 9 by the spring 14 by applying a force in the outer peripheral direction, the base removing operation is performed in the conventional manner. At this time, it is not necessary to screw the elastic body strongly into the base 9 remaining in the socket 25 in the insertion direction, so that the work of removing the base 9 can be easily performed with good workability without being restricted by a place or a height position. it can.
[0022]
In the above-described embodiment, as the rotating means 30, the operator operates the elongated body 33 by hand to apply a rotating force to the claw portions 11a and 12a, but an electric rotating means may be used. . Further, the spring 14 for applying the pressing force to the inner surface of the base 9 on the claw portions 11a and 12a is disposed between the arm portions 11 and 12, but is not limited to this, and the spring 14 is configured to apply the pressing force to the inner surface of the base 9. Any means may be used.
[0023]
【The invention's effect】
As described above, the die removing device of the present invention is such that at least a pair of claws are pressed against the inner wall of the die by applying a force in an outer circumferential direction to the inner wall of the die by a spring, and the die is rotated by rotating the claws by rotating means. Because it is removed, the elastic body does not have to be screwed strongly in the insertion direction into the base remaining in the socket when removing the base as in the past, so it is easy to work without any restrictions on the location or height position etc. The work of removing the base can be performed.
