Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a lighting device in which a lighting device with variable illumination direction is attached to a desired position on a horizontal bar of a building, and a fall prevention wire is added for safety. It is. If the lighting fixture is a standalone lighting fixture, the horizontal bar is a lighting baton.

[Background technology]

FIG. 1 shows a conventional lighting fixture in comparison with the present invention. In the figure, 1 is a U-shaped arm, and 2 is a lamp that is swingably attached to both free ends of the arm 1. Reference numeral 3 denotes a rotating support shaft having a groove 3a at the upper end and a screw 3b at the lower end, and the screw 3b is screwed into the center of the arm 1. Reference numeral 4 denotes a hanging tool having a C-shaped hook portion 4a on the upper side and a rotating support shaft 3 on the lower side. Fixed in desired position. The bolt 7 passing through the hanging tool 4 fits into the groove 3a of the rotating support shaft 3 and connects the rotating support shaft 3 and the lifting tool 4.
Concatenate. Reference numeral 8 denotes a ring-shaped projection that is welded and fixed near the U-shaped curved portion of the arm 1. Reference numeral 9 denotes a fall prevention wire that is attached at both ends to the protrusion 8 and is wrapped around the horizontal bar 5 to prevent the lamp 2 and the like from falling.

In such conventional lighting equipment, a wire 9 is required for the lighting equipment 2 to rotate once around the rotation shaft 3.
The wire 9 has to be sufficiently long, and the disadvantage is that the wire 9 can get caught on the lamp 2, etc., or get in the way when moving the appliance, but if it falls, the falling distance will be long and the impact will be large. However, there was a drawback that the protrusion 8 had to be made sufficiently strong.

[Disclosure of invention]

The present invention was devised in view of these drawbacks, and will be described below with reference to the embodiments shown in FIGS. 2 to 4.

In the figure, 1...U-shaped arm, 2...Lamp,
3...Rotating shaft, 4...Hanging tool, 5...Small bar, 6...Set screw, 7...Bolt have the same structure as the above-mentioned conventional example. However, arm 1 is composed of a pipe. Reference numeral 10 denotes a substrate consisting of an upper substrate 11 and a lower substrate 12, each having a through hole 13, 13 in the center thereof through which the rotational shaft 3 passes, and a wire through which a wire described later passes through the lower substrate 12. Insertion hole 14
is drilled. The upper substrate 11 and the lower substrate 12 are held together near the center of the arm 1 and are fixed to the rotary support shaft 3 using a bolt and a nut 15. Reference numeral 16 denotes a fall prevention wire having a ring portion 16a at one end and a hook piece 16b at the other end. The wire is inserted through the wire insertion hole 14 of the substrate 12, and the other end is wrapped around the horizontal bar 5, and the hook piece 16b is hooked around the wire 16 itself to form a loop, which is then attached to the horizontal bar 5. In addition, when the wire 16 is not attached to the horizontal bar 5, as shown in FIG.
If the ring part 6b is hooked to the ring part 16a and temporarily secured, the instrument can be easily moved.

[Effects of this invention]

As described above, the lighting fixture of the present invention is characterized in that the base plate supporting the base of the rotating shaft is fixed to the center of the arm, the ring portion on one end of the wire is inserted into the arm and positioned and attached to the above-mentioned base plate, and the other end is wrapped around a horizontal bar, and therefore has the following effects.

(1) Since the attachment end of the wire is located near the rotating shaft, the length of the wire can be shortened so that there is no problem even when the light fixture rotates, and the wire does not get caught on the fixture or hang unsightly. In addition, even if the device were to fall, the short length of the wire reduces the impact force, making it safer.

(2) Since the ring part of the wire is inserted through the arm and installed, there is no need to consider the strength of the protrusion as in the past, improving safety.

[Brief explanation of the drawing]

FIG. 1 is an overall view of a conventional lighting fixture in comparison with the present invention. Figures 2 to 4 show examples of the present invention. Figure 2 is a cross-sectional view of the entire lighting device, Figure 3 is an exploded perspective view of the main parts, and Figure 4 shows the wires being temporarily fixed. FIG.

Claims (1)

[Scope of utility model registration request] A U-shaped arm, a light fixture attached to both free ends of the arm, a rotating shaft fixed to the center of the arm, and the other end pivoted to the rotating shaft and positioned at a desired position on the horizontal par of the building. In a lighting fixture that consists of a hanging fixture that can be freely fixed to the arm, and a wire that supports the weight of the light at one end and a fall prevention wire that is wrapped around a horizontal par at the other end, the board that supports the base of the rotating shaft is fixed to the center of the arm. A lighting device characterized in that a ring portion provided at one end of the wire is inserted into the arm, positioned and attached to the substrate, and the other end is wound around a horizontal bar.
