Description

[Detailed Description of the Invention] The present invention relates to a lighting duct hanger for suspending and fixing a lighting duct for attaching lighting equipment and supplying power from a raceway laid under the ceiling.

FIG. 1 shows a configuration diagram showing a state in which the raceway 1 and the lighting duct 3 are installed on the lower surface of the ceiling.

The raceways 1 are arranged in a grid or striped manner on the lower surface of the ceiling, and are suspended by hanging fittings 12.

The lighting duct 3 is suspended from the raceway 1 by a hanger body 13', and a lighting fixture 2', an outlet, etc. are attached thereto.

In general, when laying a raceway 1 as shown in Fig. 1, the suspension pitch L is 1500 mm or 2000 mm.
It is often set to a round number of mm, and at the same time, the standard length of lighting duct type 3 is also 150 mm.
It is often set to round numbers of 0 mm and 2000 mm.

Therefore, for example, if raceway 1 is L = 2000
If the lighting duct 3 is installed perpendicular to the raceway 1, the standard length of the lighting duct 3, which is 2000 mm, will not be long enough to hang directly below the raceway 1 by the width of the raceway 1. ,−
Lighting duct 3, which has a long rank, must be cut and used.

That is, a hanger main body 1 on which the lighting duct 3 is suspended.
3', as shown in FIG. 2, is formed in a substantially U-shape and is screwed onto the lower surface of the raceway 1 with a screw 14.

The lighting duct 3 is inserted into the hanger body 13' and held there.

Further, even when the lighting duct 3' is installed diagonally with respect to the raceway 1, the hanger body 13' is attached to the hanger body 13' at an appropriate angle by using the lighting duct 3' which is one rank longer.

In the case of such a conventional example, the lighting duct 3 is used by cutting it to the required length using a rank-long lighting duct 3, which increases the cost of the lighting duct 3, requires time and effort to cut it, and cuts the end of the lighting duct 3 after it has been cut. There is a problem that the length is wasted, and the hanger body 13' is attached to the screw 14.
To attach it to raceway 1 at
It takes time and effort to drill the tapped holes, and the tips of the screws 14 inside the raceway 1 protrude and become a hindrance to internal cables.Furthermore, once the tapped holes are drilled, the position of the lighting duct 3 changes There was a problem that it was difficult to make fine adjustments.

The present invention has been proposed in view of the above-mentioned points, and when the lighting duct is hung perpendicularly or diagonally to the raceway, the installation pitch of the raceway is slightly longer than or equal to the length of the lighting duct. To provide a hanger for a lighting duct, which is capable of being freely attached even in cases where the lighting duct is installed, and which can be easily attached without requiring any special tools during construction.

Embodiments of the present invention will be described in detail below with reference to the drawings.

The raceway 1 is arranged under the ceiling and is bent into a substantially U-shaped cross section and is elongated.

The raceway 1 is laid with the opening facing upward, and the upper ends of both side pieces 4, 4 are bent inward over substantially the entire length in the longitudinal direction to form the opening edges 5, 5, respectively. It is.

In the figure, reference numeral 13 denotes a hanger body that suspends and holds the lighting duct 3 from the raceway 1. As shown in FIGS. It is composed of a duct hanger 10 and the like that hold the duct.

The holder 7 is formed in a U-shape and is made of a spring material such as spring stainless steel.

Further, the holder 7 is formed to be slightly larger than the outer shape of the raceway 1, and the upper ends of both side pieces 9, 9 of the holder 7 are curved inwardly into locking pieces that abut from the upper surface of the opening edge 5 of the raceway 1. There are 6.

The duct hanger 10 is made of the same spring material as the holder 7, and has a locking portion 11 for inserting and locking the lighting duct 3.
is approximately U-shaped.

This locking portion 11 has a predetermined size W in a direction perpendicular to the outer surface of the side piece 9 of the holder 7.

It stands out.

The mounting piece 12 other than the locking part 11 of the duct hanger 10 is located on the lower surface of the center piece 8 of the holder 7, and the center piece 8 and the mounting piece 12
is rotatably attached to the central part of the central piece 8 with a shark shaft 14.

Therefore, the upper surface of the central piece 8 of the holder 7 is formed flat.

Reference numeral 15 denotes a substantially U-shaped holding fitting that engages the locking pieces 6 on both sides of the holder 7 from above and from the sides. The holder 7 is clamped and fixed to the raceway 1 by a stopper 16 whose both end surfaces are in contact with each other.

A screw 17 is fixed upwardly in the center of the stopper 16. This screw 17 is inserted from below into an insertion hole drilled approximately in the center of the holding fitting 15, and the holding fitting 15 is inserted into the inserted screw 17. Screw on the butterfly nut 18 from the top side.

Then, the side pieces 9 and 9 of the holder 7 of the hanger body 13 are expanded outward as shown by the dashed line in FIG. Lock it in place.

Since the holder 7 is made of a springy material and is formed to be slightly larger than the outer shape of the raceway 1, it can easily hold the raceway 1 therein.

Then, with the screw 17 facing upward, the stopper 16 is brought into contact with the lower surface of both opening edges 5, 5 of the raceway 1, the presser metal fitting 15 is brought into contact with the upper part of the holder 7, and the wing nut 17 is screwed down as described above. 17, presser metal fitting 15 and stopper 1
6, the holder 7 is clamped and fixed to the raceway 1.

Since the presser metal fitting 15 and the stopper 16 are also bent into a substantially U-shape, the bent portions catch on the side of the raceway 1 or the ribs 19 on the internal opening edge 5, preventing rotation when tightening screws or other operations. There is no way you can get away with it.

Next, the lighting duct 3 is inserted into the duct hanger 10 to complete the process.

In addition, since the duct hanger 10 rotates, it can be installed even when the lighting duct 3 is perpendicular to the raceway 1 or at an angle. By rotating it, the lighting duct 3 can be constructed even directly under the raceway 1.

As described above, the present invention includes a locking piece that is bent into a substantially U-shape, has elasticity, is slightly larger than the outer diameter of the cross section of the raceway, and abuts the opening edge of the raceway from above on the upper part of both side pieces. a lighting duct which is rotatably supported on the lower surface of the holder and approximately at the center of the center piece of the holder and protrudes by a predetermined dimension in a direction perpendicular to the surface of the side piece of the holder; Since the duct hanger is inserted and locked, the lighting duct can be hung even when the raceway installation interval is equal to the length of the lighting duct. It can be easily rotated in any direction, such as halfway or in the same direction, and can support the lighting duct 1. Furthermore, to attach the holder to the raceway, simply use the elasticity of the holder to spread the side pieces and attach the lace. Because the raceway itself is simply held in place and locked, there is no need to process the raceway itself, and no special tools are required, making it easy to install. A screw is provided protruding therein, a stopper is provided that presses both sides of the retainer against the lower surface of the opening edge, the upper part of the locking piece of the holder is bridged from above, and an insertion hole is bored through which the screw is inserted. Since it is equipped with a presser metal fitting and a screw nut that is screwed into the screw of the stopper that is inserted upward through the insertion hole of the presser metal fitting, the holder and the raceway are connected after the holder is locked to the raceway. To fix the raceway, bridge the upper part of the locking piece of the holder from above, attach the stopper from below the raceway by inserting the screw into the insertion hole of the presser metal, and then screw the By screwing the duct hanger's retainer onto the raceway with a wing nut, the holder of the duct hanger is attached to the raceway using the stopper that presses against the lower surface of the opening edge of the raceway on both sides, and the presser metal fitting that presses against the opening edge from above. Therefore, it does not require any special tools or ordinary tools, and therefore it can be installed easily and quickly.In particular, this type of lighting duct hanger installed on the underside of the ceiling. Since the work is done at height, this has the advantage of being beneficial in terms of safety.

Furthermore, since it is attached to the raceway using screws, it is easy to fine-tune the position on the raceway, and since the screws do not protrude into the raceway, they do not interfere with internal cables. has.
