Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a device arm mounting structure for a decorative hanging tool.

[Background technology]

There are decorative lighting fixtures as shown in Figures 1 to 3. That is, four arms 3 are extended from the peripheral side of a device body 2 having a lamp socket 1, and a decorative hanging device 4 made of a bar welded in a cross shape is attached to the free end of each arm 3. Decorative parts 5 such as glass are hung on a decorative hanging tool 4. 6 is a lamp, and 7 is a terminal block.

By the way, the decorative hanging tool 4 has conventionally been attached to the tip of the arm 3 with bolts and nuts, and by loosening the bolts and nuts, the direction of the decorative hanging tool 4 can be arbitrarily changed to develop a design.
However, it is troublesome to accurately determine the direction, and if the bolts and nuts are loose, some external force may be applied to the decorative hanging tool 4 when installing the decorative parts.
There was a drawback that the decorative hanging tool 4 rotated when the decorative hanging tool 4 was attached to the wall.

[Purpose of invention]

The object of this invention is to provide an instrument arm mounting structure for a decorative hanging device that allows the orientation of the decorative hanging device to be changed and allows easy and reliable positioning.

[Disclosure of invention]

This idea combines a plurality of U-shaped bars in a radial manner and forms cutouts on both sides of the bars at their intersections to form a decorative hanging tool.
When attached to the arm with a nut, the arm engages with both sides of the bar while being overlapped, and engages with the notch when located between the arm bars. This allows the bolt
Even if the nut loosens to some extent, the decorative hanging tool will not rotate due to the above-mentioned engagements, and the presence of the engagement portions facilitates positioning.

An embodiment of this invention is shown in FIGS. 4 to 9. That is, a pair of bars 9 and 10 constituting the decorative hanging tool 8 have a U-shaped cross section, and one of the bars 9 has an engagement notch 1 of a predetermined width on both side pieces 9a at the center.
1, a recess 12 cut out by the width of the bar in the center of the engagement notch 11, and a caulking pawl 13 formed in this recess 12.
A hole 14 is formed at the bottom of the central part of the 0, into which the caulking claw 13 engages, and both side pieces 10 of the central part are formed.
An engagement notch 15 having the same width as the notch 11 is formed at a. Both bars 9 and 10 are connected to the holes 14 of the bar 10 by the caulking claws 13 of the bar 9 as shown in FIGS. 6 to 5.
The bar 10 is fitted into the concave part 12 of the bar 9 to form a cross shape on the same plane, and the caulking claws 13 are caulked outward to connect them, thereby eliminating the need for conventional welding and simplifying assembly. A bolt 16 is passed through a screw hole (not shown) formed at the center of the bottom of the bar 9, and the screw hole 18 at the free end of the arm 17 is passed through the tip of the bolt 16, and then tightened with a cap nut 19. 20 is a hook for hanging decorative parts.

7 to 9 show how the decorative hanging tool 8 is attached to the arm 17, and FIGS.
The figure shows the arm 17 being positioned between the arm 17 and the bar 9 and the bar 10 by loosening the cap nut 19, and then tightening the cap nut 19 to move the arm 17 into the engagement notches 11, 1.
5 is engaged. Therefore, it is easy to position the decorative hanging tool 8 with respect to the arm 17, and the decorative hanging tool 8 does not rotate even if the cap nut 19 loosens to some extent. Further, in FIG. 9, the arm 17 is stacked on one bar 9 (or 10) and engaged with both side pieces 9a of the bar 9, so that the arm 17 is also securely positioned. In this way, the decorative hanging tool 8 is rotated and positioned every 45 degrees.

In addition, the number of bars of the hanging device 8 in this invention is not limited to any number.

[Effect of idea]

As described above, the device arm mounting structure of the decorative hanging device of this invention combines a plurality of U-shaped cross-sectional bars that engage the arm in a radial and coplanar manner, and has engagement cutouts on each side of the intersection. By forming a notch, the arm overlaps the bar or engages with the notch between the bars, and the arm and the decorative hanging tool are screwed together, so the decorative hanging tool can be rotated and positioned easily and reliably. This has the effect that it does not rotate.
