Description

[Detailed Description of the Invention] The present invention relates to a hanging device for hanging lighting equipment such as Jumpria from a hanger fixed to the ceiling. The purpose of this is to simplify fixing the nut to the hanger that supports it.

To hang a lighting fixture like a Jumpria, a hanger is usually fixed to the top of the building, a nut is welded to this hanger in advance, and the bolt used to hang the lighting fixture is screwed into this nut. Equipment is hung on hangers.

However, welding a nut to a hanger requires a special nut specifically for welding, which increases the unit price in the case of small-scale production, and requires a positioning jig to weld the nut in the correct position. There are some inconveniences such as

The present invention provides a hanging device in which a nut is easily fixed to a hanger by providing a cut-and-raised claw or a cut-and-raised piece on the hanger to suppress the rotation and movement of the nut, and there is no need to use a special nut. It is something.

FIG. 1 shows a side sectional view of the hanging device of the present invention attached to a ceiling surface.

In the figure, reference numeral 1 denotes a field edge support provided on the upper part of the building, to which a field edge 2 is fixed, and to this field edge 2 a ceiling board 3 is attached.

Reference numeral 4 denotes a reinforcing bar fixed at right angles to the field edge support 1, a hanger 5 is fixed to the reinforcing bar 4 with a wood screw 6, and a nut 7 is fixed to the hanger 5.

On the other hand, a bolt 8 is screwed into a nut 7 through a hole 12 provided in the ceiling plate 3, and a decorative plate 9 fitted with the bolt 8 and a mounting bracket 10 are tightened with a nut 11 to cover the hole 12, and a lighting fixture (not shown) is installed. The lighting fixture is hung from the hanger 5 by hooking the hooking fitting 13 attached to the mounting fitting 10.

Next, the structure of the hanger 5 will be explained with reference to FIGS. 2 to 5.

Figure 2 is a perspective view of the hanger, Figure 3 is a back view of the hanger,
It is a side view and a front view C.

The hanger 5 is composed of a back plate 14, a bottom plate 15 formed by bending its lower end into a U-shape, and a front plate 16, and the front plate 16 is superimposed on the back plate 14 via an obliquely inclined slope 17.

The bottom plate 15 is provided with a through hole 18 for the bolt 8, and the nut 7 is placed on the hole 18, and as shown in FIG. Te Natsu 7
The nut 7 is fixed to the hanger 5 by being held down from above and, as shown in FIG. 2, by a pair of raised pieces 20 provided on the front plate 16 to prevent the nut 7 from rotating from both sides.

The back plate 14 of the hanger 5 and the front plate 16 superimposed on the back plate 14
There is a mounting hole 21 in the upper part of the lamp, and the lighting fixture is fixed to the reinforcing frame 4 with a wood screw 6 inserted through the hole 21 as described with reference to FIG.

A hole 22 for bolt insertion is provided in the slope 17 so that the bolt does not hit the slope 17 of the hanger 5 when the bolt 8 is screwed into the nut 7.

As shown in the developed view in FIG. 5, the hanger 5 has a through hole 18, a cut-and-raised claw 19, a cut-and-raised piece 20, and a mounting hole 21 in one metal plate.
．． It can be easily made by providing a bolt insertion hole 22 and bending it.

As described above, in the present invention, the nut is fixed to the hanger by suppressing vertical movement and rotation of the nut using the cut-and-raised pawl and cut-and-raise piece provided on the hanger, so when welding the nut to the hanger, There is no need to use a special nut like this, making it suitable for small-scale production.Also, the hanger can be made by punching and bending a single metal plate, so the structure is simple and can be made at low cost. The effect of this can be obtained.
