Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a lighting device equipped with a lighting fixture that can be slid freely along the upper circumference of a chassis, and the power supply cord is appropriately treated.

BACKGROUND ART Conventionally, a lighting device equipped with a movable lighting fixture has an arm protruding from a chassis that supports the lighting fixture.
Most of the lighting fixtures are of the type that supports rotation around the fulcrum of the arm, and there were no particular difficulties in processing the power supply cord to the lighting fixtures (Utility Model Act 1973-1).
(See Publication No. 4062).

Problems that the invention aims to solve However, when trying to realize a lighting device with a lighting fixture that can freely slide along the upper circumference of the chassis, the movement of the power supply cord to the lighting fixture becomes large, and the processing is difficult. Due to this difficulty, the present invention
This allows the power supply cord to be appropriately handled in such a case.

Means for Solving the Problems In the present invention, the power supply cord to the lighting device is located in a groove provided on the top surface of the chassis, and
A lighting device is constructed by attaching weights to appropriate places on this power supply cord.

Effects According to the present invention, since the power supply cord is weighted, it is difficult for the power supply cord to deviate from the groove, and it can move smoothly according to the movement of the lighting equipment, so that the power supply cord can be properly handled. be done.

Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings. A lighting device A serving as the main illumination includes a lamp 2 such as an annular fluorescent lamp provided on the bottom surface of a chassis 1 and covered with a globe 3. It is. At the center of the upper surface of the chassis 1, there is provided a mounting part 5 for the ceiling surface 4 that protrudes upward, and the mounting part 5 is attached to the ceiling surface 4 by an appropriate means. is provided. Also, gloves 3 and chassis 1
The attachment is carried out by suitable means such as a stiff spring type. The two lighting fixtures B serving as auxiliary lighting are located on chassis 1.
It is provided so that it can be slid freely along the upper circumference of the.

In detail, the lighting fixture B consists of an arm 7 and a lighting fixture 8 as its main elements.A substantially L-shaped support 9 is fixed to the base end of the arm 7 with screws 10, and is supported on the lower surface of the support 9. A plate 11 is fixed with screws 12. At this time, a hole 9a is provided in the horizontal part of the support 9, and the ball bearing 13 is inserted into the hole and is prevented from falling by the support plate 11, so that the ball bearing 13 protrudes upward from the side surface of the groove 6. A total of three pieces are fixed to each other with screws or the like and abut on the lower surface of the annular support surface 14. A substantially L-shaped mounting device 15 is attached to the middle of the arm 7 with screws 16, and at this time,
Insert the ball bearing 17 from above the hole 15a in the horizontal part of the mounting tool 15 so that it faces from the bottom of the hole 15a, which has a smaller diameter than the ball bearing 17, and
Abuts against the outer periphery of the top surface.

The structure of the lamp 8 is that a cylindrical hood 18 is attached to the tip of the arm 7 with a spacer 19 interposed therebetween using screws 20, and a mounting plate 22 on the top surface of the lamp body 21 is passed through a hole 18a on the top surface of the hood 18 and screws are inserted. 23 to the arm 7, and the cover 24 at the tip of the arm 7 is attached to the mounting piece 22a of the mounting plate 22 with screws 25, and the lamp body 21 is caulked to the mounting plate 22 or the like to rotate as desired in the horizontal plane. An approximately U-shaped angle 26 attached with a corner, and a cylindrical body 27 attached to the lower end of the angle 26 so as to have a desired rotation angle in a vertical plane.
, a socket support 29 provided at the top of the cylinder 27 to support the socket 28 , a reflector support 31 provided inside the cylinder 27 to support the reflector 30 , and an opening in the hood 18 . It consists of a buttful 32 attached around the part, a lamp 33, etc. Light body 2
The rotation angle in the horizontal plane of the light body 21 is determined by the position of the protrusion 26a on the upper surface of the angle 26 in the circular arc hole 22b of the mounting plate 22, and the rotation angle in the vertical plane of the lamp body 21 is determined by the position of the protrusion 26a on the upper surface of the angle 26 in the circular arc hole 22b of the mounting plate 22. The movement of the body 27 is regulated by the buttful 32 in the hood 18, and the protrusion 26a is also slightly passed through the arcuate hole 7a of the arm 7. Lighting equipment B
The power supply cord 34 is taken out from the outer surface of the attachment part 5 (located in the groove 6), is placed in the groove 6 with a weight 35 such as lead attached to an appropriate place, and is inserted into the notch at the base end of the arm 7. Pass through the upper surface of the arm 7 from 7b, enter the cover 24, and connect the hole 7c of the arm 7 and the hole 26 that also serves as a caulking to the mounting plate 22 on the upper surface of the angle 26.
b. Through the hole 18a of the hood 18, the socket 2
Connected to 8.

According to the above configuration, the lighting fixture B can smoothly slide along the upper circumference of the chassis 1, and since the power supply cord 34 has the weight 35 at the appropriate position, the power supply cord 34 may deviate from the groove 6, causing the lighting fixture B to slide smoothly. There is little risk of impeding movement or deteriorating the appearance.

The movement of the lighting fixture B is restricted by the side edge of the arm 7 coming into contact with a movable stopper 36, which has an upwardly facing piece 36a at its tip and whose base end is fixed at one point on the outer periphery of the upper surface of the chassis 1 so that it can rotate. is,
Since the movable stopper 36 moves by a predetermined rotation angle depending on which side edge of the arm 7 it comes into contact with,
When there is only one lighting fixture B, the lighting fixture can be positioned over the entire circumference of the chassis 1 by approximately 360°. When there are two lighting fixtures B, any one of the lighting fixtures can be arbitrarily placed over the entire circumference of the chassis 1 by approximately 360°.

Effects of the Invention As described above, according to the present invention, the power supply cord of a lighting device that slides along the upper circumference of the chassis can be accommodated with less risk of protruding from the groove on the top surface of the chassis, and can be accommodated with large movements of the power supply cord. This has the effect of eliminating the risk of impairing the movement of the lighting fixture or deteriorating its appearance.
