In the conventional pendant lighting fixture, when the position of the pendant lighting fixture is changed by moving the ceiling outlet 18 or when the lighting lamp 13 is shaken by the wind of air conditioning, the glove 13b and the glove 13b of the adjacent lighting lamp 13 strike each other. There is a risk of damage.
Moreover, in the conventional pendant lighting fixture, the suspension position from the ceiling of each illumination lamp 13 is uniquely determined by the length of the pendant cable 12, and the illumination lamp 13 cannot be set to an arbitrary suspension position.
In view of such a problem, the present invention is a pendant lighting fixture in which the lighting lamp 13 is suspended from the ceiling by a plurality of pendant cables 12 hanging from the socket 11. The purpose is to provide.
Moreover, it aims at providing the pendant lighting fixture which can adjust the hanging position from the ceiling of each lighting lamp 13 to arbitrary positions.

The invention described in claim 1
A pendant luminaire that extends multiple pendant cables from a socket connected to a ceiling outlet, and suspends an illumination lamp from the ceiling with each pendant cable,
A belt is mounted on the outer peripheral surface of the globe as a buffering means for preventing the gloves of adjacent illumination lamps from directly contacting each other.

  According to a second aspect of the present invention, in the pendant lighting device according to the first aspect, the belt is a ring-shaped belt made of soft plastic or rubber.

  The invention according to claim 3 is the pendant lighting device according to claim 1, further comprising a bundling tool for bundling and tightening the plurality of pendant cables, loosening the pendant cable between the socket and the bundling tool, It is characterized in that the hanging position from the ceiling of the illumination lamp can be adjusted by maintaining slackness by friction between the bundling tool and the pendant cable and between the pendant cables.

The invention according to claim 4 is the pendant lighting fixture according to claim 3,
A rubber or soft plastic ring is used as the bundling tool, and a plurality of pendant cables are inserted into the ring.

  According to the first aspect of the present invention, even if the illumination lamp is shaken, the belt serves as a cushioning material, and the gloves of the adjacent illumination lamps are not in direct contact with each other.

  According to the second aspect of the present invention, since the belt is made of soft plastic or rubber and has a ring shape, when the belt is attached to the glove of the illumination lamp, the belt expands and contracts and adheres to the glove. Therefore, the belt can be quickly and easily attached to the glove.

According to invention of Claim 3, the hanging position of the illumination lamp suspended from a ceiling with a pendant cable can be adjusted by loosening the pendant cable between a socket and a bundling tool. Moreover, in the pendant lighting fixture provided with the several bundling tool, the pendant cable between a bundling tool and a bundling tool can be loosened, and the hanging position from the ceiling of an illumination lamp can be adjusted.
And since slack is maintained by the friction between a bundling tool and a pendant cable, the hanging position of a plurality of illumination lamps can be adjusted and maintained with a simple operation that only loosens the pendant cable.
Since the hanging position of the illumination lamp can be set to an arbitrary height by adjusting the slack amount of the pendant cable, the decoration effect as the interior of the pendant lighting fixture can be enhanced.

  According to the fourth aspect of the present invention, since the rubber or soft plastic ring is used as the bundling tool, the slack can be reliably maintained by the friction between the ring and the pendant cable. Easy to use because of its simple structure.

It is another partial expansion perspective view which shows the illumination lamp and ring-shaped belt of the pendant lighting fixture. It is a perspective view which shows the conventional pendant lighting fixture.

  The present invention will be described below with reference to the drawings. FIG. 1 shows a pendant lighting apparatus 10 according to an embodiment of the present invention. The pendant lighting device 10 includes a socket 11, a plurality of pendant cables 12, an illumination lamp 13 connected to the lower end of each pendant cable 12, and two soft plastic rings 14 as a bundling tool. A bundle of cables 12 is inserted through the ring 14.

  The ceiling side end portions of the plurality of pendant cables 12 are covered with a spherical cover 15, and are connected inside the cover 15 with a cord 16 hanging from the socket 11. Each pendant cable 12 has the same length.

  The socket 11 is detachably connected to a sealing outlet 18 slidably incorporated in a duct rail 17 fixed to the ceiling. By connecting the socket 11 to the ceiling outlet 18, each illumination lamp 13 is suspended from the ceiling by the pendant cable 12.

  As shown in an enlarged view in FIG. 2, an annular groove 14a is formed in the middle of the outer peripheral portion so that the ring 14 is easily elastically deformed. When the bundle of pendant cables 12 is inserted into the center hole 14b of the ring 14, the bundle of the pendant cables 12 is tightened so that appropriate friction is generated between the ring 14 and the pendant cable 12. It has the required inner diameter and material according to the number and material.

  The illumination lamp 13 includes a lamp socket 13a connected to the lower end of the pendant cable 12, and a glass globe 13b that is detachably attached to the lamp socket 13a. A ring belt 19 is attached to the globe 13b. FIG. 3 shows an enlarged view of the ring belt 19. The ring-shaped belt is made of a transparent soft plastic and has flexibility and stretchability. Therefore, the ring-shaped belt is in close contact with the glove and can easily adjust the mounting position on the glove.

  The configuration of the pendant lighting device 10 according to the present embodiment is as described above. As shown in FIG. 4, the two rings 14 are slid up and down along the pendant cable 12 to change the position. By forming a slack 12a in the pendant cable 12 between the ring 14 and the socket 11, or as shown in FIG. 5, a slack 12a is formed in the pendant cable 12 between the upper ring 14 and the lower ring 14. Thereby, the hanging position of the illumination lamp 13 suspended from the ceiling by the pendant cable 12 can be adjusted, and the decoration effect as the interior of the pendant lighting fixture 10 can be enhanced. Since slackness is maintained by friction between the ring 14 and the pendant cable 12, the hanging position of the plurality of illumination lamps 13 can be adjusted to an arbitrary position and maintained by a simple operation that only loosens the pendant cable 12.

Since the ring-shaped belt 19 is attached to the globe 13b of the illumination lamp 13, as shown in an enlarged view in FIG. 6, the ring-shaped belt 19 can be used as a cushioning material to avoid direct contact between the adjacent globe 13b, It is possible to prevent the globe 13b from being damaged by the collision between the globe 13b and the globe 13b.
Further, as shown in FIG. 7, it is possible to avoid direct contact between the globe 13b and the lamp socket 13a, and it is possible to prevent the globe 13b from being damaged by the contact between the globe 13b and the lamp socket 13a.

In this embodiment, a soft plastic ring 14 is used as a bundling tool. Instead, a bundle of pendant cables 12 is inserted into a rubber ring or a coil spring-like member, or a string-like ring is used. A bundle of pendant cables 12 may be bound by a member.
One or three rings 14 may be provided in accordance with the length of the pendant cable 12.

  In this embodiment, a transparent ring-shaped belt made of soft plastic is used as the buffering means, but it may be opaque or colored to enhance the decoration as an interior of the pendant lighting fixture. It is also possible to enhance the operational effect as a buffer means by attaching a plurality of ring-shaped belts to one glove.
