Description

[Detailed Description of the Invention] This invention relates to a mounting device for a lighting fixture with an arm.

In general, a lighting fixture with an arm that is attached to a wall or the like has a main body 1, as shown in Figure 1.
, an arm 2 formed by bending a hollow member into an L-shape, and a universal joint 3 that connects both 1 and 2, and is attached to a wall surface 5 or the like using a fixing member 4. The above-mentioned arm-equipped lighting fixture 6 includes a universal joint portion 3
Although it is possible to freely adjust the direction of the lighting fixture body 1 by means of a swiveling mechanism, it is insufficient to illuminate a desired area over a wide range. The lighting fixture main body 1 is rotated to a desired location.

Figure 2 shows the insertion hole 8 of the bent end 7 of the arm 2.
A fixing member 10 with mounting screw seats 9, 9 provided on both sides of the
In order to prevent the arm 2 from falling off and to regulate the turning angle, an elongated hole 11 is bored in the circumferential direction of the insertion hole 8, and a bolt 12 is inserted into the elongated hole 11 and screwed into the bent end 7. I'm letting you do it.

By the way, with the fixing member 10 described above, when the arm-equipped lighting fixture 6 is attached, the end face of the bent end portion 7 of the arm 2 and its inner circumferential surface are exposed, resulting in a poor appearance. Further, if the wall thickness of the arm 2 is thin, the screw hole is likely to be deformed by the shock at the end of rotation, which poses a problem in terms of strength.Furthermore, the bolt 12 may loosen due to vibration and may fall off at an unexpected time.

In view of the above-mentioned drawbacks, this invention aims to improve this by having a mounting hole that is attached to a wall or the like by an appropriate means, has a large-diameter part and a small-diameter part, and has a large-diameter part facing upward and a small-diameter part facing upward. A fixing member formed downward and provided with a locking protrusion at a predetermined position on the large diameter part, and an arm whose L-shaped bent end is inserted into the mounting hole of the fixing member through the small diameter part and into the large diameter part. a cap attached to the tip of the bent end of the arm so as to close the upper opening of the mounting hole; and a connecting pin inserted through the cap and the arm so that both ends protrude further from each other, A lighting fixture mounting device in which both ends of the connecting pin are located within a large diameter portion having a locking protrusion, so that the arm can be rotated within a range where the connecting pin is locked to the locking protrusion, and the device is as follows: An embodiment of this invention will be described below with reference to the case where the arm-equipped lighting fixture shown in FIG. 1 is attached.

FIG. 3 shows a perspective view of a lighting fixture mounting device;
In the figure, 7 is the bent end of the arm 2 of the arm-equipped lighting device 6, and 5 is the wall surface to which it is attached.

Reference numeral 13 denotes a fixing member having a mounting hole 16 consisting of a large diameter part 14 and a small diameter part 15 through which the bent end part 7 can be inserted, and in which the large diameter part is formed upward and the small diameter part is formed downward. It has screw seats 17, 17 for attaching to 5 etc. A cap 18 is fitted into the large diameter portion 14 of the fixing member 13 so that the upper opening is closed, and is composed of a top plate 19 and a cylindrical portion 20 attached to the outer periphery of the bent end portion 7. Reference numeral 21 denotes a connecting pin that connects the arm 2 and the cap 18, and as shown in FIG. Therefore, a turning gap is provided within the large diameter portion 14 between both ends and the inner peripheral surface. Incidentally, the connecting pin can also be replaced with a screw. Reference numeral 23 denotes a locking member protruding from a predetermined position of the step between the large diameter portion 14 and the small diameter portion 15 of the fixing member 13 in order to regulate the turning angle of the connecting pin 21, that is, the turning angle of the arm 2 and the lighting fixture body 1. The above-mentioned both ends 22 of the connecting pin 21,
22 and is locked.

In the embodiment, the arm-equipped lighting fixture 6 is mounted on the wall surface 5.
The fixing member 13 has a mounting hole 1 in order to attach it to the
6 are provided with screw seats 17, 17 parallel to the screw seats 25, 2 of the fixing member 24, as shown in FIG.
5 is provided at right angles to the mounting hole 26.

To attach the arm-equipped lighting fixture 6 to the wall surface 5 etc. using the lighting fixture mounting device configured as described above, first,
The fixing member 13 is attached and fixed to the wall surface 5 or the like with the large diameter portion 14 facing upward. Next, the bent end portion 7 of the arm 2 is inserted into the small diameter portion 15, the cylindrical portion 20 of the cap 18 is attached to the inserted bent end portion 7, and the connecting pin 21 is inserted to connect the two. After that, the installation of the arm-equipped lighting fixture 6 is completed by simply making the lengths of both ends 22 and 22 of the connecting pin 21 protrude equally and fitting the cap 18 into the large diameter part 14.

On the other hand, when attaching the arm-equipped lighting fixture 6 to a ceiling or the like using the fixing member 24, the arm-equipped lighting fixture 6 is first attached to the fixing member 24, and then the fixing member 24 is attached to the ceiling or the like.

In addition, in this invention, the cylindrical portion of the cap can be installed so as to cover the outer peripheral surface of the arm, or it can also be installed so as to be inserted into the arm.

As described above, according to this invention, it is easy to attach the arm to the fixing member, and the bent end surface of the arm and its inner peripheral surface can be covered with the cap, resulting in a good appearance.
In addition, since both ends of the connecting pin are located inside the large diameter part, the connecting pin will never come off the arm or cap due to vibration, so the mounting part will not come loose due to vibration, so the lighting fixture will not come loose unexpectedly. It does not fall off, and the shock at the end of the swing of the arm-equipped lighting fixture can be loaded by shearing on two sides of the continuous pin, so it has excellent strength.
