Description

[Detailed description of the invention] This invention relates to a protective net for a lighting fixture with a reflective shade.

Conventionally, this type of protection net has been shown in FIGS. 1 to 3. In the figure, 1 is a single mesh made up of a plurality of arc-shaped horizontal wires 2 and vertical wires 3 to which these horizontal wires 2 are welded, and 4 is a seat plate welded to the upper and lower ends of one side of this single mesh 1. The above-mentioned net unit 1 is made by superimposing three sets of connecting plates 5 over the vertical wires 3, 3 as shown in FIG.
is tightened to assemble a cylindrical protective net, and the upper end of this protective net is attached to the arm portion 8 of the hanging metal fitting 7 in the form of three arms. 9 is a reflective hat.

In the conventional protective net constructed as described above, when manufacturing the net alone, it is difficult to position the intersection of the horizontal wire rods 2 and the vertical wire rods 3 when welding, so other jigs are required, and the welding points are difficult to locate. There were a lot of things and it took a lot of work. Furthermore, when welding the seat plate 4 to the mesh alone, a jig was required as described above because the mesh was curved. Furthermore, the net itself is bulky, so it has the disadvantage of requiring bulky packaging during transportation.

This device was developed to eliminate the drawbacks of the conventional ones as mentioned above, and it can be easily assembled without any welding, and it can be packed into a small size without being bulky during transportation. The purpose of this invention is to provide a protective net for lighting equipment with a reflective shade.

An embodiment of this invention will be described below with reference to the drawings. In Figs. 4 to 7, reference numerals 10 and 11 are two strips made of metal plates, etc., and the lower ends of both strips 10 and 11 are rotatable by caulking the shaft 12 of one of the strips 10. It is linked to Reference numeral 13 indicates a plurality of equally spaced U-shaped notch grooves formed on one side of one of the strip plates 10 (the left side in FIG. These are a plurality of V-shaped notch grooves that merge with the notch groove 13. 15 uses a plurality of sets of the above strip plates 10 and 11;
This is an annular wire material in which notch grooves 13 and 14 which overlap and face each other are combined and sandwiched. The protective net assembled as described above is suspended by screws 18 tightening holes 10a and 11a formed at the upper ends of the respective strips 10 and 11 to arm pieces 17 that protrude radially from the mounting bracket 16. In addition, 19 is a reflective shade, and mounting bracket 1
It is fixed at the center of the bottom surface of 6.

To assemble the protective net of this invention constructed as described above, first, the band plates 10 and 11 are opened using the shaft portion 12 at the lower end as a fulcrum, and then each of the opposing notch grooves 1 is opened.
3 and 14 are combined to sandwich the annular wire 15, and the upper ends of the respective strip plates 10 and 11 to which the annular wire 15 is attached are fastened to the respective arm pieces 17 of the mounting fitting 16 with screws 18.

As described above, according to this invention, the protective net is made up of a plurality of annular wires, two strips each holding the annular wires, and a mounting bracket that screws together the upper end of each strip. Therefore, it can be easily assembled with good workability without requiring any conventional welding assembly. Furthermore, since the product is disassembled during transportation, it can be packed in a smaller size without being bulky.
