本考案はワイヤーで吊り下げた電動昇降式照明装置の改
良に関する。[Detailed Description of the Invention] The present invention relates to an improvement of an electric lifting type lighting device suspended by a wire.
従来比較的軽量の電動昇降式照明装置において通常は一
本のワイヤーで照明器具を吊り下げ昇降自在に支持して
いる。BACKGROUND ART Conventionally, in a relatively lightweight electric lifting type lighting device, a lighting fixture is usually suspended from a single wire and supported so as to be able to rise and fall freely.
しかし照明器具の外形あるいは重量が大きくなると、一
本のワイヤーでは照明器具のバランスをとることができ
ず、また重量を支えることができない。However, as the external size or weight of the lighting equipment increases, a single wire cannot balance the lighting equipment or support the weight.
そこで照明器具の外形あるいは重量が大きい構造の場合
は第１図に示すように、照明器具１の上部に動滑車２を
設は同動滑車２にワイヤー３を配設しそのワイヤー３を
照明器具１の上方に設けた駆動軸４に支持し、照明器具
１を昇降している。Therefore, if the lighting equipment has a structure with a large external size or weight, as shown in Fig. 1, a movable pulley 2 is installed on the top of the lighting equipment 1, and a wire 3 is arranged on the movable pulley 2, and the wire 3 is connected to the lighting equipment. The lighting fixture 1 is supported on a drive shaft 4 provided above the lighting fixture 1, and is raised and lowered.
しかし外形あるいは重量が大きい照明器具１を支持した
上記構造により、ワイヤー３が摩耗し万一照明器具１が
落下した場合、大きな事故の原因となる。However, due to the above-mentioned structure supporting the lighting fixture 1 which has a large external shape or weight, the wire 3 is worn out and if the lighting fixture 1 were to fall, this could cause a serious accident.
そこで本考案は比較的簡単な改良で安全性の増大する電
動昇降式照明装置を提供することを目的とする。Accordingly, an object of the present invention is to provide an electrically-operated lifting type lighting device that increases safety through relatively simple improvements.
以下本考案を第２図および第３図について説明する。The present invention will be explained below with reference to FIGS. 2 and 3.

駆動軸であって、モータ１９に連動しである。In the figure, 11 is a plurality of lighting fixtures fixed to the fixture mount 12, and 13 and 14 are a plurality of lighting fixtures fixed to the fixture mount 12 at regular intervals.
The movable pulley placed on the top of 2, 15.16 is the instrument mounting body 1
A fitting tube 17 is provided on the upper surface of 2, and 17 is a lighting fixture 1 that can be raised and lowered.
A box body 18 provided above 1 is a drive shaft provided inside the box body 17, and is interlocked with a motor 19.

２３を構成しである。20.21 is the lower surface of the box body 17, and the fitting tubes 15, 1
A fitting rod 22 provided at a location corresponding to 6 has one end supported on the drive shaft 18 provided above, and the other end supported on the pulley 13.1.
4 and is supported on the drive shaft 18, and a part of the wire 22 located between the pulleys 13 and 14 has an enlarged portion 23.
膨大部２３としては、例えばステンレス製の金属材で樹
皮した円筒体を用いる。As the enlarged portion 23, a cylindrical body made of, for example, a stainless steel metal material is used.
２４，２５は滑車１３．１４に近接して設けたストッパ

でき、利用価値が大きい。As mentioned above, the present invention has two pulleys spaced apart from each other on the top surface of the lighting equipment, one wire is placed from the drive shaft to the two pulleys, and the wire is placed between the two pulleys. A part of the wire is provided with an ampulla, and the configuration is such that the ampulla does not move anywhere other than between the two pulleys, so even if the wire wears out due to use and is cut, the ampulla will remain close to the pulleys. It has great utility value as it can prevent a major accident from being latched onto a strapper.
