〔技術分野〕
この考案は、昇降式照明器具に関するものであ
る。[Detailed description of the invention] [Technical field] This invention relates to an elevating type lighting fixture.
例えば、宴会場、ホール等の空間で灯具部分を
昇降させ、さらに回転機能を加えることによつ
て、固定式照明器具では得ることのできない演出
効果を生み出すことが考えられている。
For example, it is being considered that in spaces such as banquet halls and halls, lighting fixtures can be moved up and down, and by adding a rotating function, they can create dramatic effects that cannot be achieved with fixed lighting fixtures.
しかしながら、従来、灯具を回転させ昇降させ

動作に伴つて回転させるものが考えられた。これ
によれば、前記のようなトラブルがなくすぐれた
照明上の意匠的効果を現出できしかも構造を簡単
にすることができる。 However, in the past, when the lamp was rotated to be raised and lowered, electrical troubles such as wire breakage occurred due to bending or twisting of the cord, and the design became unsightly. In addition, mechanically driven devices such as motors are used as the power to rotate the light fixtures, and in addition, large-scale equipment is required to prevent the above-mentioned problems, which is adding to the cost burden. There was a problem. On the other hand, for example,
No. 14314), a system was proposed in which a cord connected to a lifting device was spirally wound around a cable, and the lamp was rotated as the cable moved up and down. According to this, the above-mentioned troubles can be avoided, an excellent lighting design effect can be achieved, and the structure can be simplified.
しかし、索条が長くなるとコードも長くなるた
め灯具側にたるみが生じて外観が悪くなつたり灯
具の回転にぶれを生じ、また灯具の回転速度の調
整が困難であるという欠点があつた。 However, as the length of the cable becomes longer, the cord also becomes longer, which causes slack on the lamp side, resulting in poor appearance, blurring of the rotation of the lamp, and difficulty in adjusting the rotation speed of the lamp.
この考案の目的は、索条が長くなつても灯具へ
コードのたるみおよび灯具の回転のぶれを防止で
きるとともに灯具の回転速度の調整が可能な昇降

The lifting type lighting equipment of this invention includes a lamp body having a lamp, a lifting cable from which the lamp body is suspended, and a lifting cable that is wound spirally around the lifting cable and whose lower end is connected to the lamp main body. and a helical cord made of a springy power supply cord that generates rotational force as the lifting cable expands and contracts due to the vertical movement of the lifting cable; and a receiver that fixes the intermediate portion and receives the rotational force of the spiral thread.
昇降用索条を引上げて螺旋条を収縮させると、
灯具本体はフリーであるので螺旋条はその径を大
きくする方向に昇降用索条を中心として回転す

伸ばすと、螺旋条はその径を小さくする方向に昇
降用索条を中心として回転し、これらの回転によ
り灯具が回転する。 When the elevating cable is pulled up and the spiral thread is contracted,
Since the lamp body is free, the spiral thread rotates around the lifting cable in a direction that increases its diameter. On the contrary, when the elevating cable is let out and the spiral thread is extended, the helical thread rotates around the elevating cable in a direction that reduces its diameter, and these rotations rotate the lamp.
螺旋条は回転力を発揮するように最初からばね

め、灯具側の螺旋条の垂みおよび灯具の回転のぶ
れを防止できるので昇降用索条を長くすることが
でき、また受具の上側の螺旋条の長さの調整が可
能なため灯具の回転速度を調整できる。 Since the spiral strip has spring properties from the beginning so that it can exert rotational force, the spiral strip does not become unsightly deformed, and even if the spiral strip is used as a power supply cord, no electrical trouble occurs. . Therefore, there is no need for large-scale equipment to prevent such troubles. Furthermore, since a motor or the like is not used to obtain the rotational force, only a helical strip with a simple spring property is used, so the overall structure is greatly simplified. Furthermore, since the support that fixed the middle part of the spiral strip is attached to the lifting cable so that it can move up and down, it is possible to prevent the spiral thread on the lighting equipment side from sagging and the rotation of the lighting equipment to be unstable, thereby making the lifting cable longer. In addition, since the length of the spiral strip on the upper side of the holder can be adjusted, the rotation speed of the lamp can be adjusted.

と同時成形することが挙げられる。Embodiment An embodiment of this invention will be explained based on FIGS. 1 to 3. In the figure, 1 is the lamp body, 2
1 is a lifting cable such as a wire connected to the center of the upper end of the lamp body 1; 3 is a lamp attached to one or more places on the lamp body in a state that it is deviated from the lifting cable 2; 4 is a lamp socket. This is a spiral wire for rotating the lamp body, which has spring properties and is wound spirally around the lifting cable 2 while being connected to the lifting cable 2. In this embodiment, it also serves as a power supply cord for the lamp. As a means of imparting springiness to the power supply cord,
Examples include heat treatment or simultaneous molding with a hard rubber material or bar material.
昇降用索条２の下端近くに受金具を実施例とす

として回転する。Operation As described above, when the lifting cable 2 is pulled up and the spiral 4 is contracted, the lamp body 1 is free, so the spiral 4 moves around the lifting cable 2 in the direction of increasing its diameter. Rotate as . On the other hand, when the elevating cable 2 is let out and the spiral thread 4 is extended, the spiral thread 4
rotates around the lifting cable 2 in a direction that reduces its diameter.

軌跡はすぐれた意匠的効果を発揮する。 Since the lamp 3 is attached to the lamp body 1 in a state that is deviated from the lifting cable 2, when the spiral thread 4 rotates as it goes up and down, the lamp 3 rotates around the lifting cable 2 accordingly. Draw a spiral. lamp 3
Because it emits brilliance, the trajectory of the radiant spiral movement has an excellent design effect.
もし、受具５がないとすれば、第２図Ａに示す

容易に行える。 In addition, by changing the vertical position of the support 5, the stroke of the upper part of the spiral strip 4 can be adjusted.
Thereby, the rotation speed of the lamp body 1 can be adjusted. If the support 5 is configured to be freely displaceable with respect to the lifting cable 2, the rotational speed of the lamp body 1 can be easily set.
第３図のＡ，Ｂは宴会場などにおいて、昇降式

According to this invention, as the lamp is moved up and down, a rotational force is generated in the spiral strip, causing the lamp to rotate. Moreover, since the support that fixes the middle part of the spiral strip is installed on the cable so that it can move up and down, it is possible to prevent the spiral strip from hanging on the lighting equipment side and the rotation of the lighting equipment from wobbling, making it possible to make the lifting cable longer. In addition, since the length of the spiral strip on the upper side of the receiver can be adjusted, there is an effect that the rotational speed of the lamp can be adjusted.
