この発明は昇降式照明器具等に適用される伸縮
自在コードに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a retractable cord applied to an elevating type lighting fixture or the like.

し被覆部材８で一体形成して断面扁平形状とな
し、その長手方向Ａをら旋軸方向Ｂとなるように
ら旋巻きしている。９は昇降取手である。 Liftable lighting fixtures are shown in Figures 1 to 3. That is, a wire 3 is suspended from an elevator 2 installed on the ceiling 1, a device main body 4 is suspended from the lower end of the wire 3, and a telescopic cord (curl cord or spiral cord) 5 is wound around the wire 3 to connect the device main body 4. Connecting. As shown in FIGS. 3 and 4, this stretchable cord 5 has two conductive wires 6 and 7 arranged in parallel and integrally formed with a covering member 8 to have a flat cross-section. It is spirally wound so that it becomes B. 9 is a lifting handle.

縮自在コード５の収縮時には第４図のようにすき
間Ｓを発生して外観を損ねたり、、第５図のよう
な弛みＰを生じるという問題があつた。 However, in this elevating type lighting fixture, the maximum height or minimum total length H 1 (Fig. 1) and the minimum height or maximum total length H 2 of the fixture due to the telescoping cord 5 are limited.
Due to the limitations shown in FIG. 2, if the maximum overall length H 2 is set large, the minimum overall length H 1 also becomes large, which impairs the lifting function. Further, when the elastic cord 5 is contracted, there is a problem that a gap S is generated as shown in FIG. 4, which impairs the appearance, and a slack P as shown in FIG. 5 is generated.
したがつて、この発明の目的は、収縮時の全長
を短くすることができる伸縮自在コードを提供す
ることである。 Therefore, an object of the present invention is to provide a stretchable cord whose total length when contracted can be shortened.
この発明の第１の実施例を第６図に示す。すな
わち、この伸縮自在コードは、導線６，７を被覆
する被覆部材１０が断面扁平形状であつてら旋巻
きされるとともに、前記断面扁平形状の長手方向
A′の一端側がら旋軸Ｂに接近するように長手方
向A′がら旋軸Ｂに対して傾斜したものである。 A first embodiment of this invention is shown in FIG. That is, in this stretchable cord, the covering member 10 that covers the conducting wires 6 and 7 has a flat cross-section and is wound spirally, and
The longitudinal direction A' is inclined with respect to the helical axis B so that one end side of A' approaches the helical axis B.
このように構成したため、収縮時においては第
６図のようにら旋軸Ｂの方向に対して斜めに重り

長H3をH3＜H1と短縮できる。また傾斜状態で重

も外部水平方向からはすき間S′が見えず外観的に
も優れる。 With this structure, when contracting, the axial length of one turn can be made smaller than before by overlapping diagonally with respect to the direction of the helical axis B as shown in Fig. 6, and therefore, when expanding, the axial length of one turn can be made smaller than before. While keeping the length the same as the conventional one, the total length H 3 at the time of contraction can be shortened to H 3 <H 1 as shown in Fig. 7. In addition, since they overlap in an inclined state, even if there is a gap S' as shown in FIG. 6, the gap S' is not visible from the outside horizontal direction, resulting in an excellent appearance.

１の実施例と同様である。 A second embodiment of the invention is shown in FIG. That is, in this elastic cord, a groove 11 is formed on the covering member 10 between the conducting wire 6 and the conducting wire 7, and a spring reinforcing wire 12 is inserted thereinto, thereby reinforcing the elasticity of the elastic cord. be. The other configurations are similar to the first embodiment.

１の実施例と同効果がある。 With this configuration, it is possible to prevent the loosening P due to the weak elasticity of the cord as shown in FIG. 5, and it is possible to maintain a good appearance in each expansion and contraction state. Other effects are the same as those of the first embodiment.

The covering member that covers the conducting wire has a flat cross-sectional shape and is spirally wound, and the longitudinal direction is inclined with respect to the helical axis so that one end side in the longitudinal direction of the flat cross-sectional shape approaches the helical axis. , it has the effect that the total length in the extended state can be made the same and the total length in the contracted state can be shortened.
