Description

本発明は、家屋の天井などに設けられた吊具本体にワイヤーを介して照明器具を吊り下げる照明器具用吊具に関する。   The present invention relates to a hanging fixture for a lighting fixture that suspends a lighting fixture via a wire on a hanging fixture body provided on a ceiling or the like of a house.

図１６〜図１７に示す照明器具用吊具２００は、吊具本体２０１に収納されているアジャスタ２０２により吊下げ高さを調整できるタイプのものである。
このアジャスタ２０２は、ワイヤー２０３を上方へ自由に押し上げることが可能で、ワイヤー２０３の下方への引き出しを解除ボタン（図示せず）を押すことで可能とするものである。
このアジャスタ２０２は、通常時には、内部に備えた把持部材（図示せず）でワイヤー２０３を側方から押さえ付けることで照明器具２０５の重量を支えている。 16 to 17 is of a type in which the hanging height can be adjusted by an adjuster 202 housed in a hanging body 201.
The adjuster 202 can freely push the wire 203 upward, and can pull the wire 203 downward by pressing a release button (not shown).
Normally, the adjuster 202 supports the weight of the luminaire 205 by pressing the wire 203 from the side with a gripping member (not shown) provided inside.

さらに、照明器具用吊具２００は、ワイヤー２０３のうち、吊具本体２０１側の端部に玉部２０６が設けられ、玉部２０６でワイヤー２０３がアジャスタ２０２の把持部材から抜け落ちることを防止している。   Further, the lighting fixture 200 is provided with a ball portion 206 at an end of the wire 203 on the side of the hanging device main body 201, and the ball portion 206 prevents the wire 203 from falling off the holding member of the adjuster 202. Yes.

また、ワイヤー２０３のうち、照明器具２０５側の端部に玉部２０８および玉部２０９が設けられ、玉部２０８がワイヤー２０３から外れた場合でも、玉部２０８で照明器具２０５の重量を支えるようにしている（例えば、特許文献１参照）。
特開２００４−５５３０５号公報 Moreover, the ball part 208 and the ball part 209 are provided in the edge part by the side of the lighting fixture 205 among the wires 203, and even if the ball part 208 remove | deviates from the wire 203, it will support the weight of the lighting fixture 205 with the ball part 208 (For example, refer to Patent Document 1).
JP 2004-55305 A

しかし、アジャスタ２０２の内部では、アジャスタ２０２の把持部材でワイヤー２０３を側方から押さえ付けているため、誤って大きな衝撃が加えられた場合など、まれにワイヤー２０３に断線が発生することが考えられる。   However, since the wire 203 is pressed from the side by the holding member of the adjuster 202 inside the adjuster 202, it is considered that the wire 203 rarely breaks when a large shock is accidentally applied. .

万一、ワイヤー２０３が断線しかけた場合でも、その状態を外部から視覚的に確認することができない。
このため、そのまま継続して使用されてワイヤー２０３が断線してしまうことが懸念される。この場合、照明器具用吊具２００で照明器具２０５を保持することが難しい。
また、照明器具２０５側でも、玉部２０８の直上部でワイヤー２０３が断線した場合など、照明器具用吊具２００で照明器具２０５を保持することが難しい。 Even if the wire 203 is almost broken, the state cannot be visually confirmed from the outside.
For this reason, there is a concern that the wire 203 is disconnected as it is continuously used as it is. In this case, it is difficult to hold the lighting fixture 205 with the hanging fixture for lighting fixture 200.
In addition, on the side of the lighting fixture 205, it is difficult to hold the lighting fixture 205 with the hanging fixture for lighting fixture 200, such as when the wire 203 is disconnected just above the ball portion 208.

図１８の照明器具用吊具２１０は、図１７に示すアジャスタ２０３を除去したものである。
この照明器具用吊具２１０も、玉部２０６や玉部２０８の根元でワイヤー２０３が断線した場合に、照明器具用吊具２１０で照明器具２０５を保持することが難しい。 The hanging fixture 210 for lighting fixtures of FIG. 18 removes the adjuster 203 shown in FIG.
