BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a spotlight on a construction surface.

[0002]

2. Description of the Related Art As a spotlight to be constructed on a construction surface such as a ceiling, an arm 2 is suspended from a flange 1 attached to the ceiling as shown in FIG. Some are attached. Then, the power supply line 4 is drawn into the flange 1 from behind the ceiling, and power is supplied to the lighting body 3 through the flange 1 and the arm 2.

FIG. 8 shows a specific structure of a flange 1 of a spotlight of this type. In the case of this spotlight, the bottomed cylindrical flange 1 whose lower surface is closed is fixed to the ceiling surface by a disk-shaped mounting plate 5. The mounting plate 5 has a hole 6 for inserting the power supply line 4 in the center, and a fixing hole 7 for fixing the mounting plate 5 to the ceiling surface with a wood screw at the periphery of the hole 6 and fixing the flange 1 from the lower surface. A plurality of rod-shaped mounting screws 8 for protruding are provided. Flange 1
, The arm 2 is fixed by a hex nut 9,
, And a terminal block 11 for connecting the power supply line 4 is attached to the end of the lead wire 10. A plurality of insertion holes 12 through which the mounting screws 8 of the mounting plate 5 pass are formed on the lower surface of the flange 1.

The mounting of the spotlight on the ceiling is performed as follows. First, the mounting plate 5 is fixed to the ceiling surface with a wood screw while the power line 4 is passed through the hole 6.
, The mounting screw 8 is passed through the insertion hole 12, the flange 1 is attached to the mounting plate 5, and a cap nut 13 is screwed into a portion of the mounting screw 8 protruding from the lower surface of the flange 1. Attach the spotlight to the ceiling.

[0005]

However, with the above structure, there is a problem that the work of passing the mounting screw 8 through the insertion hole 12 of the flange 1 becomes very troublesome. That is, since the power line 4 of this type of spotlight is generally very hard and hardly bent, the mounting screw 8
When the power line 4 hits the hex nut 9 when the flange 1 is rotated to match the position of the flange 1 with the position of the insertion hole 12 of the flange 1, the position of the mounting screw 8 and the position of the flange 1 are changed.
The position of the insertion hole 12 cannot be adjusted, and there is a problem that it takes time and effort to mount the spotlight on the ceiling.

The present invention has been made in view of the above points, and an object of the present invention is to provide a spotlight which can be easily mounted on a construction surface.

[0007]

According to the present invention, in order to achieve the above object, a hole for passing a power supply line of a mounting plate is formed at a position shifted from the center, and the terminal block is attached to an arm and fixed to a peripheral portion. It is provided with a fixed fixing plate.

[0008]

According to the present invention, the hole for passing the power supply line of the mounting plate is formed at a position shifted from the center as described above, so that the power supply line does not hit a member in the flange such as a hexagon nut, and the arm is connected to the arm. By providing a fixing plate to which the terminal block is fixed on the peripheral part, when the position of the mounting screw of the mounting plate and the insertion hole of the flange are aligned, the force for preventing the rotation of the flange by the power supply line is weakened. The position of the mounting screw of the mounting plate and the insertion hole of the flange can be easily adjusted, and the mounting on the construction surface can be easily performed.

[0009]

(Embodiment 1) FIGS. 1 to 3 show an embodiment of the present invention. In this embodiment, the overall structure is almost the same as that described in the section of the prior art. In this embodiment, the hole 6 for passing the power line 4 of the mounting plate 5 is shifted from the center as shown in FIG. It is characterized in that it has a fixing plate 14 which is formed at an inclined position, is fixedly attached to the arm 2, and has a terminal block 11 fixed to the periphery thereof. As shown in FIG. 2, an insertion hole 15 is formed at the center of the fixing plate 14 so as to fit into the tip of the arm 2. The piece 16 is cut and raised. Here, the terminal block 11 is attached so that the power supply line 4 is inserted from the lateral direction.

In this embodiment, when the mounting screw 8 of the mounting plate 7 fixed to the ceiling 17 is passed through the insertion hole 12 of the flange 1, the power supply line 4 is inserted into the terminal block 11, and By rotating, the position of the mounting screw 8 and the position of the insertion hole 12 of the flange 1 are adjusted. At this time, the fixing plate 14 rotates together with the rotation of the flange 1, whereby the power supply wire 4 is wound on the fixing plate 14 along the claw pieces 16 shown in FIG. That is, in the present embodiment, the hole 6 for passing the power line 4 of the mounting plate 5 is formed at a position shifted from the center, so that the power line 4 does not hit a member in the flange 1 such as the hexagon nut 9 and the like. Since the rotational force with the center of the flange 1 as a fulcrum is applied to the power supply line 4, the power supply line 4 can be bent without requiring a conventional force, and the position of the mounting screw 8 and the insertion hole 12 can be easily determined. Adjustment can be performed and the construction time can be shortened.

In the above-described embodiment, the power supply line 4 is wound around the fixing plate 14 to reduce the bending force of the power supply line 4, but the power supply line 4 itself is completely bent. If the structure is not allowed, more favorable workability can be obtained. In this case, the fixing plate 14 fixed to the arm 2 may be rotatable with respect to the arm 2. That is, in this case, even if the flange 1 is rotated, the position of the terminal block 11 and the power supply line 4 is kept constant by the rotation of the fixing plate 14. 4 does not act to bend. Therefore, in this case, the positioning of the mounting screw 8 and the insertion hole 12 can be more easily performed, and it can be expected that the construction time is further reduced.

(Embodiment 2) FIGS. 4 to 6 show another embodiment of the present invention. In this embodiment, when the fixing plate 14 is rotatable with respect to the arm 2 in the first embodiment, if the fixing plate 14 is rotated greatly, the lead wire 10 may be disconnected. Things.

For this reason, in this embodiment, a cylindrical spacer 19 with a flange provided at the lower portion shown in FIG. 5A is attached to the base inserted into the flange 1 of the arm 2. 4 is attached to the arm 2 with the fixing plate 14 shown in FIG. In addition, the sliding contact body 20 is mounted through the arm 2 in a hole 30 drilled in the center.

Here, the sliding contact body 20 is made of a molded body 21 shown in FIG. 5B made of an insulating material such as a resin and a molded body 21 shown in FIGS. 5C and 5D. Two annular power supply fittings 22a and 22b made of a conductive material to be attached
Consists of The power supply fitting 22a is partially cut out, and a connection piece 23 for connecting the lead wire 10 upward from one end of the cutout portion.
The power supply fitting 22a is housed in a groove 24 formed on the upper part of the molded body 21, and the connecting piece 23 is
In the vertical groove 25 formed continuously.

A part of the power supply fitting 22b is also notched, and a connection piece 26 protruding inward is formed at the base of the notch, and is housed in a groove 27 formed at the lower part of the molded body 21. The connection piece 2 is inserted into a through hole 28 formed in the groove 27.
6 is fitted. In the present embodiment, one line for supplying power to the spotlight uses the lead wire 10 and the other line uses the arm 2 formed of a conductive material. The connecting piece 26 of the metal fitting 22b is made to contact the arm 2.

From the surface of the terminal block 11 fixed on the fixing plate 14 opposite to the surface to which the power supply wire 4 is connected, a pair of conductive materials made of a conductive material that slides on the respective outer peripheral surfaces of the power supply fittings 22. The contact piece 29 is protruded. The spacer 1
When the hexagonal nut 9 is screwed onto the tip of the arm 2 with the fixing plate 14, the fixing plate 14 and the sliding contact body 20 attached to the arm 2, the spacer 19 and the sliding contact body 20 are fixed to the arm 2 and fixed. A plate 14 is rotatably attached to the arm 2. The structure of the other members is the same as that described in the first embodiment.

In this embodiment, the fixing plate 1 of the first embodiment is used.
Similarly to the case where the power supply line 4 is made rotatable, the rotation of the fixing plate 14 causes the power supply line 4 and the terminal block 11 to which the power supply line 4 is connected.
And the force to bend the power supply line 4 does not affect the alignment between the mounting screw 8 and the insertion hole 12, and the alignment between the mounting screw 8 and the insertion hole 12 is simplified. And the construction time can be shortened. Moreover, in the case of this embodiment, the lead wire 10 is not twisted even if any rotation is applied to the flange 1, and disconnection of the lead wire 10 can be prevented.

In the above case, the arm 2 is used as the other of the power supply line to the spotlight. However, the lead wire 10 may be used, of course. 22.

[0019]

[Effects of the Invention] As described above, in the present invention, the hole for passing the power line of the mounting plate is formed at a position shifted from the center.
Since the power line does not hit the hexagon nut or other member in the flange, it has a fixing plate that is attached to the arm and the terminal block is fixed around the periphery, so the position of the mounting screw on the mounting plate and the insertion hole of the flange can be adjusted. When aligning, the power to prevent the rotation of the flange due to the power line can be weakened, so that the mounting screw on the mounting plate can be easily aligned with the through hole of the flange,
There is an advantage that the spotlight can be easily attached to the construction surface.
