Description

[Detailed explanation of the idea] The present invention relates to a lighting fixture mounting device.

Conventionally, lighting fixtures such as chanterias are used by being suspended from the ceiling, but the lighting fixtures are attached to the tip of arm A, which projects radially from the fixture body P, and are supported perpendicularly to arm A, as shown in Figure 1. A lamp body C and a decorative body are attached to the upper and lower parts of the support pipe B.

Then, the lead wire is guided through a guide groove provided in the arm A, guided into the support pipe B through the insertion hole of the support pipe B, and further connected to the lamp body C.

On the other hand, the lamp body C and the decorative body are attached at the same time when the support pipe B is attached to the arm A by tightening a nut.

However, in such a situation, when the support pipe B is attached to the arm A, if the vertical position of the support pipe B is not determined or if it rotates, the lead wire may be bent or come off the guide groove of the arm A and be exposed. There is a danger that the lead wires will be damaged or safety will be compromised.
It has poor workability.

It is also inconvenient for assembling a large number of parts in the same process, such as when attaching a lamp body C or a decorative body.

The present invention was developed in view of these points, and includes forming a locking recess that looks into the pipe insertion hole of the arm, and providing a locking protrusion on the support pipe that is inserted into the pipe insertion hole. The support pipe is inserted into the pipe insertion hole and the locking recess and the locking protrusion are engaged to prevent the support pipe from being pulled out and to prevent the support pipe from rotating. This is designed to facilitate installation work.

Next, an embodiment of the present invention will be described with reference to FIGS. 2 to 5.

Reference numeral 1 denotes an arm, which is attached to an instrument main body (not shown) and projects radially.

A pipe insertion hole 2 is formed at the tip of this arm 1, and the pipe insertion hole 2 is formed on the upper surface of this arm 1.
A gutter-shaped lead wire guide groove 3 is formed which communicates with the pipe insertion hole 2, and the bottom of the end of the lead wire guide groove 3 that is exposed to the pipe insertion hole 2 is cut out to communicate with the pipe insertion hole 2 on both sides and below. A locking recess 4 having a wall surface is formed therein.

Reference numeral 5 designates a support pipe, which is formed into a hollow pipe having threaded portions 6 at its upper and lower ends, and is inserted into the pipe insertion hole 2 and attached to the arm 1.

The support pipe 5 protrudes short upwardly from the arm 1 and long downwardly, and has a lead wire insertion hole 7 formed opposite to the lead wire guide groove 3, and also faces the locking recess 4. A locking protrusion 8 that locks into the locking recess 4 and prevents movement in the downward and lateral directions is formed on the portion, and the locking protrusion 8 is connected to the support pipe 5 as shown in FIG.
It is formed by screwing a screw 10 into a screw hole 9 formed in .

In addition, 11 is a lamp body, and this lamp body 11 is a dish-shaped lamp body section 12.
A dish-shaped chassis 15 is fixed to a flange 13 formed on the periphery of the opening with a flange 16 formed on the periphery of the opening via a reflective plate 14.
At that time, the lamp holder 17 is attached at the same time, the annular lamp 18 is attached to the lamp holder 17, and the lamp 18 and the reflector 14 are attached to the tip of the support 19 which is erected and fixed in the center of the chassis 15. A glove 20 covering the top is attached with screws 20a.

Further, 21 is a decorative body, and this decorative body 21 is the support pipe 5.
22 is a decorative pipe, and this decorative pipe 2
2 is between the arm 1 and the lamp segment 12 and the arm 1
and a pair of nuts 23, which are screwed into the threaded portions 6 at the upper and lower ends of the support pipe 5, and are connected to the arm 1 through the support pipe 5. Light body 11. Tighten and attach the decorative pipe 22 and decorative body 21.

In addition, 24 is a decorative piece screwed onto the lower end of the support pipe 5.

In addition, 25 is a lead wire, which connects a power source and a lamp 18 (not shown).
It is guided above the lamp segment 12 through the lead wire guide groove 3 and the lead wire insertion hole 7 so that the lead wire can be connected to the lamp segment 12.

To assemble, first insert the lead wire 25 guided into the lead wire guide groove 3 of the arm 1 into the lead wire insertion hole 7 of the support pipe 5, and then guide the lead wire 25 through the support pipe 5. do.

Then, this support pipe 5 is inserted into the pipe insertion hole 2 of the arm 1.
is inserted from above, and the locking protrusion 8 is locked in the locking recess 4 via the lead wire guide groove 3.

Furthermore, the decorative pipe 22 and the decorative body 21 are sequentially inserted from below the support pipe 5, and the nut 23 is screwed onto the lower end of the support pipe 5 and tightened between the nut 23 and the locking protrusion 8. Attach and fix.

Next, the lamp section 12 of the lamp body 11 is fitted into the upper end of the support pipe 5 via the decorative pipe 22, and the lamp body 11 is attached to the arm 1 by tightening and fixing with the nut 23.

In this way, the lamp body 11. The decorative body 21 is attached via the decorative pipe 22, and finally the decorative screw 24 is screwed onto the support pipe 5 to complete the assembly. This prevents downward removal and rotation, making the work smoother and preventing the third
As shown in the figures, the lead wire insertion hole 7 is positioned so as to accurately oppose the lead wire guide groove 3, and the lead wire 25 can be wired in a predetermined direction without any difficulty.

Note that the locking protrusion 8 of the support pipe 5 may be formed with a bulging protrusion 26 below the lead wire insertion hole 7 as shown in FIG.
Further, as shown in FIG. 7, a cut protrusion 27 may be formed at right angles downward from the lead wire insertion hole 7, and since these protrusions 26 and cut protrusions 27 can be formed by press working, they are easy to manufacture. It is easy and can reduce the number of parts.

In addition, in the case of a cut-and-raised protrusion, the cut-and-raised part should be inserted into the lead wire insertion hole 7.
It can be used as

According to the present invention, a locking protrusion is formed on the support pipe, and a locking recess is formed on the arm to engage with the locking protrusion that looks into the pipe insertion hole through which the support pipe is inserted. The pipe can be prevented from being pulled out and rotated, the lead wires can be wired in the specified way, and the work of installing the light body and decorative body at the upper and lower ends of the support pipe can be shared, making it easy to break due to heavy objects. The light body can be installed safely and reliably, and work can be done safely, smoothly, and quickly.

Further, since no external force is applied to the lead wire, there is no risk of damage.
