Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hanging lighting fixture.

[Conventional technology]

Conventionally, as shown in Fig. 4, a lamp is equipped with a lamp and a built-in electrical component such as a socket, which is connected to two wires 1 that are fixed to a hanging device body (not shown) fixed to a mounting surface such as a ceiling. 2 is known. Note that 3 is a power cord.

[Problem that the invention attempts to solve]

However, with such hanging lighting equipment,
When the lamp 2 is tilted, the wires 1 are moved one by one or the length is adjusted to eliminate the tilt.

[Means for solving problems]

The hanging type lighting fixture according to the present invention is equipped with lighting electrical components and a lamp attached with two hanging cords whose upper ends are latched to a hanging fixture body fixed to a mounting surface, and is suspended from the two hanging cords. An adjustment device for adjusting the length of the hanging string between the hanging device main body and the lamp is provided near the lower end of at least one of the hanging strings, and the lighting device is movable in a direction substantially perpendicular to the direction in which the two hanging strings are connected. The lower ends of the two suspension strings are locked directly or via an adjustment tool to a support that supports the suspension, and the adjustment tool locks the lower ends of the suspension strings at one end and allows the other end to freely rotate around the support. It is composed of an engaged adjustment body and an adjustment operation body that rotates and stops the adjustment body at an arbitrary position.

[Effect]

In the hanging type lighting device according to the present invention, the lighting device is moved in a direction substantially perpendicular to the direction in which two hanging strings fixed to the support body are connected, and the hanging string is adjusted by adjusting the adjusting device provided on at least one of the hanging strings. By changing the length, it is possible to easily adjust the inclination of the lamp in all directions, front, back, left, and right. Since it is composed of an adjusting body and an adjusting operation body that rotationally stops the adjusting body at an arbitrary position, the hanging cord will not be twisted when adjusting the length of the hanging cord, and there is no risk of damage to the hanging cord due to twisting.

[Embodiment] FIGS. 1 to 3 show an embodiment of the present invention.

Wires 1, 1, which are two hanging cords that are suspended from the suspension main body (not shown), are inserted through long holes 4, 4 provided in the lamp 2, respectively, and their lower ends are secured to the support 9. The elongated holes 4, 4 are formed in a direction substantially perpendicular to the direction in which the two wires 1, 1 secured to the support body 9 are connected. In addition, the lamp 2 has long holes 4, 4.
Similarly, an adjustment knob insertion hole 5 and a movable knob insertion hole 6 are provided in the straight line connecting the two wires 1, 1, each having an oval shape with a longer diameter in the substantially long angle direction. A moving knob 8 provided approximately at the center of the support 9 is inserted into the moving knob insertion hole 6 so that the support 9 can be moved. One of the two wires 1, 1 locked to the support 9 is locked directly to the support 9, and the other is connected to the support 9 through an adjustment tool.
It is locked to. The adjustment tool is constructed as follows. Wire 1 inserted through long hole 4 of lamp 2
The lower end of the support body 9 is inserted into the suspension string insertion hole 13 and is locked to the other end of an adjustment plate 11, which is an adjustment body whose one end is locked to the support body 9. The vicinity of the end of the adjustment plate on the side where the wire 1 is not locked is bent into a substantially L shape and is engaged with a square hole provided in the support body 9 to form a hinge portion 12, so that the adjustment plate 11 becomes a hinge portion. It is rotatable around 12. A screw 10 is provided between the suspension string insertion hole 13 of the support body 9 and the square hole in which the hinge portion 12 of the adjustment plate 11 is engaged, and the knob 7, which is an adjustment operation body having a male thread at the bottom, is screwed. are combined. The upper end of the adjustment knob 7 is inserted into the adjustment knob insertion hole 5 of the lamp 9 to change the screwing position of the screw from outside the lamp 5, and the lower end of the adjustment knob 7 is in contact with the adjustment plate 11 to prevent the screw from tightening. The length of the wire 1 is adjusted by rotating the adjusting plate 11 by changing the screwing position.

[Effect of idea]

As described above, according to the present invention, the inclination of the lamp can be easily adjusted by moving the lamp back and forth and adjusting the length of at least one hanging string, and the hanging string does not get twisted when adjusting the length of the hanging string. , there is no risk of damage to the hanging string due to twisting.
