上記構成において、照明器具１をＡ位置からＢ位置に移動させる場合、作業者３０がロープ材４を引張ると、第２のローラ８が、滑車または第１のローラ６側に引き寄せられ、該第２のローラ８が取付けられた補助アーム部材３が、支点部材７中の支点周りに回動変位する。該補助アーム部材３の回動変位に付随して、該補助アーム部材３に結合された主アーム部材２も回動変位する。該主アーム部材２の回動変位により、その第１の端部側（アーム先端側）が上昇移動し、照明器具１を上昇させる。補助アーム部材３及び主アーム部材２が回動変位を続け、所定の回動変位量に達すると、その位置で該補助アーム部材３は保持部材５に保持される。この保持位置で、主アーム部材２は略水平状態となり、照明器具１はＢ位置とされる。   In the above configuration, when the lighting apparatus 1 is moved from the A position to the B position, when the operator 30 pulls the rope member 4, the second roller 8 is drawn toward the pulley or the first roller 6, and the first The auxiliary arm member 3 to which the second roller 8 is attached is pivotally displaced around the fulcrum in the fulcrum member 7.

図２において、５１は、保持部材５内で補助アーム部材３の第２の端部側（アーム先端側）を入り込ませる凹状部５１ａを有する第１の部分、５２は、保持部材５内で該凹状部５１ａ側に上記補助アーム部材３の上記第２の端部側を案内する第２の部分、５３は、保持部材５内で上記第１の部分５１の上記凹状部５１ａの入口部（開口部）５１ｂを覆う第３の部分、５４は、該第３の部分５３に結合されたばね等の弾性部材、５５は、装置基材１０へ保持部材５を固定する固定部である。   In FIG. 2, reference numeral 51 denotes a first portion having a concave portion 51 a that allows the second end side (arm tip side) of the auxiliary arm member 3 to enter the holding member 5, and 52 denotes the inside of the holding member 5. A second portion 53 for guiding the second end side of the auxiliary arm member 3 toward the concave portion 51 a side, 53 is an inlet portion (opening) of the concave portion 51 a of the first portion 51 in the holding member 5. Part) A third part covering 51 b, 54 is an elastic member such as a spring coupled to the third part 53, and 55 is a fixing part for fixing the holding member 5 to the apparatus substrate 10.

上記構成において、照明器具１をＡ位置からＢ位置に移動させる場合は、図２（ａ）に示すように、作業者３０の操作によるロープ材４の引張り外力に基づき、補助アーム部材３が、支点部材７側に係合された該補助アーム部材３の第１の端部側（アーム根元側）を支点に（イ）位置から回動変位し、その第２の端部側（アーム先端側）部分が保持部材５の上記第２の部分５２の位置（（ロ）位置）に達すると、該第２の端部側部分は該第２の部分５２の表面に接して案内され、第１の部分５１の外表面部を経て、第３の部分５３の表面に当接する（（ハ）位置）。該当接した該第２の端部側部分は、ロープ材４の引張り外力に基づくその移動変位力が弾性部材５４の弾性復元力よりも大きいために、弾性部材５４を変位させることで第３の部分５３をａ位置からｂ位置に変位させ、上記凹状部５１ａの入口部（開口部）５１ｂに隙間を形成させ、該隙間から該凹状部５１ａ内に進入する（（ニ）位置）。進入後、作業者３０がロープ材４の引張り外力を弱めると、照明器具１や主アーム部材２や補助アーム部材３の自重などに基づき補助アーム部材３の該第２の端部側部分が該第３の部分５３から離れて（ホ）位置に移動する。該第２の端部側部分が該第３の部分５３から離れると、該第３の部分５３は弾性部材５４の弾性復元力により戻り変位して、凹状部５１ａの入口部（開口部）５１ｂを再び覆う。補助アーム部材３の該第２の端部側部分は、該凹状部５１ａ内では、照明器具１や主アーム部材２や補助アーム部材３の自重などに基づき（ホ）位置からさらに移動し、該凹状部５１ａの底面部で移動を停止し、該底面部の停止位置に保持される（（ヘ）位置）。補助アーム部材３の該第２の端部側部分の、上記（イ）位置から（ヘ）位置に至る一連の変位動作は、支点部材７側に係合された該補助アーム部材３の第１の端部側（アーム根元側）を支点とした回動変位動作として行われる。   In the above configuration, when the lighting fixture 1 is moved from the A position to the B position, the auxiliary arm member 3 is based on the tensile external force of the rope member 4 by the operation of the operator 30 as shown in FIG. The auxiliary arm member 3 engaged with the fulcrum member 7 is pivotally displaced from the position (A) with the first end side (arm base side) of the auxiliary arm member 3 as a fulcrum, and the second end side (arm tip side). ) Portion reaches the position ((B) position) of the second portion 52 of the holding member 5, the second end side portion is guided in contact with the surface of the second portion 52, and the first The portion 51 comes into contact with the surface of the third portion 53 through the outer surface portion ((C) position). Since the moving displacement force based on the tensile external force of the rope member 4 is larger than the elastic restoring force of the elastic member 54, the second end side portion in contact with the second end side portion is displaced by displacing the elastic member 54. The portion 53 is displaced from the position a to the position b, and a gap is formed in the inlet portion (opening) 51b of the concave portion 51a, and enters the concave portion 51a through the gap ((d) position). When the operator 30 weakens the pulling external force of the rope member 4 after entering, the second end side portion of the auxiliary arm member 3 is caused by the weight of the lighting fixture 1, the main arm member 2, or the auxiliary arm member 3. It moves away from the third portion 53 to the position (e). When the second end portion is separated from the third portion 53, the third portion 53 is returned and displaced by the elastic restoring force of the elastic member 54, and the inlet portion (opening portion) 51b of the concave portion 51a. Cover again. The second end side portion of the auxiliary arm member 3 is further moved from the position (e) based on the weight of the lighting fixture 1, the main arm member 2, and the auxiliary arm member 3 in the concave portion 51a, The movement is stopped at the bottom surface of the concave portion 51a and held at the stop position of the bottom surface ((f) position). A series of displacement operations from the position (A) to the position (F) of the second end side portion of the auxiliary arm member 3 is performed by the first movement of the auxiliary arm member 3 engaged with the fulcrum member 7 side. This is performed as a rotational displacement operation with the end portion side (arm base side) as a fulcrum.

上記一連の変位動作の経路のうち、（ロ）位置から、（ハ）位置を経て（ニ）位置に至る経路においては、該補助アーム部材３の該第２の端部側部分は、（イ）位置と（ロ）位置を通る直線上から偏移した状態で変位し、（ホ）位置から（ヘ）位置に至る経路においては再び、上記（イ）位置と（ロ）位置を通る直線上に復帰した状態で変位する。主アーム部材２は、上記補助アーム部材３の回動変位動作に付随して、支点部材７側に係合された該主アーム部材２の第２の端部側（アーム根元側）を支点とした回動変位動作を行い、その第１の端部側（アーム先端側）が上昇移動することで、照明器具１をＡ位置からＢ位置に移動させる。   Of the series of displacement movement paths described above, in the path from the (b) position to the (d) position through the (c) position, the second end side portion of the auxiliary arm member 3 is ) Position and (b) The position is shifted from the straight line passing through the position, and in the route from (e) position to (f) position, again on the straight line passing through position (b) and position (b). Displaces after returning to the position. The main arm member 2 has a second end side (arm base side) of the main arm member 2 engaged with the fulcrum member 7 side as a fulcrum in association with the rotational displacement operation of the auxiliary arm member 3. The lighting fixture 1 is moved from the A position to the B position by performing the rotational displacement operation and moving the first end side (arm tip side) upward.

一方、照明器具１をＢ位置からＡ位置に移動させる場合は、図２（ｂ）に示すように、作業者３０によりロープ材４に引張り外力が与えられると、補助アーム部材３が回動変位し、その第２の端部側（アーム先端側）部分が、保持部材５の凹状部５１ａ内の底面部の停止位置（（イ）位置）を離れ、（ロ）位置を経て（ハ）位置に移動する。該（ハ）位置では補助アーム部材３の第２の端部側（アーム先端側）部分は、第３の部分５３に当接し、弾性部材の弾性復元力にうち勝って該第３の部分５３を変位させて、該凹状部５１ａの入口部（開口部）５１ｂに隙間を形成させ、該第３の部分５３に当接したまま該隙間から該凹状部５１ａの外側に出る（（ニ）位置）。補助アーム部材３の第２の端部側部分（アーム先端側部分）は、ロープ材４の引張り外力によりさらに、該第３の部分５３に当接したまま移動変位し（（ホ）位置）、最後に、該第３の部分５３への当接が解放される（ヘ）位置に至り、該（ヘ）位置で停止する。
補助アーム部材３の第２の端部側（アーム先端側）部分の上記（ハ）位置から上記（ホ）位置への移動のとき、保持部材の第３の部分５３は、弾性部材５４の弾性復元力に抗してａ位置からｃ位置に回動変位する。 On the other hand, when the luminaire 1 is moved from the B position to the A position, as shown in FIG. 2B, when an external force is applied to the rope member 4 by the operator 30, the auxiliary arm member 3 is rotationally displaced. Then, the second end side (arm tip side) portion leaves the stop position ((A) position) of the bottom surface portion in the concave portion 51a of the holding member 5 and passes through the (B) position (C) position. Move to. In the (c) position, the second end side (arm tip side) portion of the auxiliary arm member 3 abuts on the third portion 53 and overcomes the elastic restoring force of the elastic member, thereby the third portion 53. Is displaced to form a gap in the inlet (opening) 51b of the concave portion 51a, and comes out of the concave portion 51a from the gap while being in contact with the third portion 53 ((d) position) ). The second end side portion (arm tip side portion) of the auxiliary arm member 3 is further displaced while being in contact with the third portion 53 due to the tensile external force of the rope member 4 ((e) position), Finally, it reaches the (f) position where the contact with the third portion 53 is released, and stops at the (f) position.
When the second end side (arm tip side) portion of the auxiliary arm member 3 is moved from the (C) position to the (E) position, the third portion 53 of the holding member is elasticized by the elastic member 54. It is rotationally displaced from position a to position c against the restoring force.

補助アーム部材３の第２の端部側（アーム先端側）部分が、（ホ）位置から（ヘ）位置に移動することで該第２の端部側部分（アーム先端側部分）の該第３の部分５３への当接が解放されると、該第３の部分５３は弾性部材５４の弾性復元力により戻り変位して、凹状部５１ａの入口部（開口部）５１ｂを再び覆う。その後、作業者３０がロープ材４の引張り外力を弱めると、該補助アーム部材３及び主アーム部材２は、照明器具１や主アーム部材２や補助アーム部材３の自重などに基づき回動変位する。このため、該補助アーム部材３の第２の端部側（アーム先端側）部分は、上記（ヘ）位置から、保持部材５の第１の部分５１の外表面部の（ト）位置を経、第３の部分５３の表面部の（チ）位置、（リ）位置及び（ヌ）位置を経て、再び第１の部分５１の表面部の（ル）位置を通り、さらに第２の部分５２の表面部の（ヲ）位置を経、やがて該保持部材５を離れてさらに（ワ）位置に変位する。主アーム部材２は、該補助アーム部材３とともに支点周りに回動変位してその第１の端部側（アーム先端側）を移動させ、照明器具１をＢ位置からＡ位置に移動させる。補助アーム部材３の該第２の端部側部分の、図２（ｂ）における上記（イ）位置から（ワ）位置に至る一連の変位動作も、支点部材７側に係合された該補助アーム部材３の第１の端部側（アーム根元側）を支点とした回動変位動作として行われる。   The second end side (arm tip side) portion of the auxiliary arm member 3 moves from the (e) position to the (f) position, so that the second end side portion (arm tip side portion) of the second end side portion (arm tip side portion) is moved. When the contact with the third portion 53 is released, the third portion 53 is returned and displaced by the elastic restoring force of the elastic member 54 and covers the entrance (opening) 51b of the concave portion 51a again. Thereafter, when the operator 30 weakens the tensile external force of the rope member 4, the auxiliary arm member 3 and the main arm member 2 are rotationally displaced based on the weight of the lighting fixture 1, the main arm member 2, and the auxiliary arm member 3. . For this reason, the second end side (arm tip side) portion of the auxiliary arm member 3 passes through the (g) position of the outer surface portion of the first portion 51 of the holding member 5 from the (f) position. Then, after passing through the (h) position, (re) position, and (nu) position of the surface portion of the third portion 53, it passes again through the (le) position of the surface portion of the first portion 51 and further to the second portion 52. After passing through the (wo) position of the surface portion, the holding member 5 is eventually released and further displaced to the (wa) position. The main arm member 2 rotates and displaces around the fulcrum together with the auxiliary arm member 3 to move the first end side (the arm tip side), and move the luminaire 1 from the B position to the A position. A series of displacement operations of the second end side portion of the auxiliary arm member 3 from the position (A) to the position (W) in FIG. 2B is also performed by the auxiliary arm engaged with the fulcrum member 7 side. This is performed as a rotational displacement operation with the first end side (arm base side) of the arm member 3 as a fulcrum.

上記該一連の変位動作の経路のうち、（ハ）位置から、（ニ）位置、（ホ）位置、（ヘ）位置、（ト）位置、（チ）位置、（リ）位置、（ヌ）位置及び（ル）位置を経て（ヲ）位置に至る経路においては、該補助アーム部材３の該第２の端部側部分は、（イ）位置、（ロ）位置及び（ハ）位置を通る直線上から偏移した状態で変位し、（ヲ）位置から（ワ）位置に至る経路においては再び、上記（イ）位置、（ロ）位置及び（ハ）位置を通る直線上に復帰した状態で変位する。   Of the series of displacement movement paths, from (c) position to (d) position, (e) position, (f) position, (g) position, (h) position, (re) position, (nu) In the path from the position and the (le) position to the (wo) position, the second end side portion of the auxiliary arm member 3 passes through the (a) position, the (b) position, and the (c) position. Displacement in a state deviated from the straight line, and in the path from the (wo) position to the (wa) position, the state is restored again to the straight line passing through the positions (b), (b) and (c). Displace at.

上記本発明の実施形態によれば、昇降式照明装置において、装置構成の簡易化、装置の小型化及び低コスト化に加え、照明器具１の昇降操作の容易化等が可能となる。特に、主アーム部材２に対する補助アーム部材３の相対的長さを調整することにより、ロープ材４の必要な引張り外力を調整することができる。また、主アーム部材２と補助アーム部材３は、９０°以下の開角をもって結合されるため、補助アーム部材３を必要な傾角をもって安定に保持部材５により保持した状態で、主アーム部材２を略水平に保つことができる。また、第１のローラ６に動滑車を用いた場合はロープ材４の必要な引張り外力を軽減することができる。   According to the embodiment of the present invention described above, in the lifting type illumination device, in addition to simplification of the device configuration, reduction in size and cost of the device, the lifting operation of the lighting fixture 1 can be facilitated. In particular, by adjusting the relative length of the auxiliary arm member 3 with respect to the main arm member 2, the necessary tensile external force of the rope member 4 can be adjusted. Further, since the main arm member 2 and the auxiliary arm member 3 are coupled with an opening angle of 90 ° or less, the main arm member 2 is held in a state where the auxiliary arm member 3 is stably held by the holding member 5 with a necessary inclination angle. It can be kept almost horizontal. Further, when a moving pulley is used for the first roller 6, the necessary tensile external force of the rope member 4 can be reduced.
