(e) Embodiment 1 is a main body unit of a two-lamp type hanging illumination light 2, in which two circular-type fluorescent tubes 3, 3 are arranged in parallel, and has a main body case 4 on the upper part that has parts necessary for lighting. Furthermore, a thin rectangular shade 5 is provided to cover these two fluorescent tubes 3, 3.

6 is a cord for suspending this main unit 1 from the ceiling etc. and for supplying power to the main unit 1; 7
1 is a cord storage and positioning device, and this device 7 is composed of a mounting frame 8, a cord storage case 9, and a cord stopper 10.

The mounting frame 8 has an elliptical shape, and has screw holes 1 on both sides for inserting mounting screws 11 into the main body case 4.
2, an insertion hole 14 formed in the center of the substrate 13, and a peripheral edge of the insertion hole 14 raised up to the height of a rising wall 15 and extending from the upper end of this raised wall 15. It has an engaging peripheral edge 16 formed around the center of the insertion hole 14.

Further, the cord storage case 9 includes a cylindrical cord storage section 18 with a downward opening and a cord insertion hole 17 at the upper base through which the cord 6 is latched and inserted through the cord stopper 10 at a predetermined position. and a protruding edge 19 circumferentially extending in the outer circumferential direction, and the storage portion 18 is attached by hooking and engaging the engaging peripheral edge 16 with the hooking upper surface 19a of the protruding edge 19. It protrudes loosely from the insertion hole 14 of the frame 8.

Furthermore, 20 is a lower surface 1 for hooking of the engagement peripheral edge 16.
6a has a wavy groove as a jagged portion on the lower surface provided in the radial direction over the entire circumference, and 24' is a protruding edge 19.
A concave groove formed on the inner peripheral side of the upper surface 19a for hooking, 2
Reference numeral 1 denotes a triangular protrusion as a jagged upper surface formed on the outer peripheral side of the upper surface 19a for hooking, and the engagement peripheral edge 1
6 and the protruding edge 19, the triangular protrusion 21 fits into any part of the wave-shaped groove 20, thereby preventing rotation of the mounting frame 8 and the cord storage case 9. This constitutes a blocking mechanism. Furthermore, since the wave-shaped groove 20 is provided over the entire circumference of the lower hooking surface 16a, the mounting frame 8 and the cord storage case 9 can be accurately positioned at any rotational position.

Further, reference numeral 22 denotes a detachment prevention projection provided on the outer wall of the cord storage portion 18, and when the cord storage housing 9 is fitted into the mounting frame 8 and integrated, the corrugated groove 20 of the engagement peripheral edge 16 is inserted. The engaging end portion 16b extending downward from the inner circumferential side is movable between the detachment prevention protrusion 22 and the protruding edge portion 19, and in this way, the mounting frame 8 and the cord storage case 9 are connected to each other. Since these parts are rotatably integrated, these parts will not be separated when the lighting lamp 2 is packed, and there is no risk of them being lost.

The mounting frame 8 is fixed with screws 11 to a mounting hole 23 drilled on the upper surface of the main body case 4 of the main unit 1 at a position where the weight of the main unit 1 as a whole can be balanced. When it is hung from the ceiling of a room in this state, the engaging peripheral edge 16 of the mounting frame 8 is latched onto the protruding edge 19 of the cord storage case 9 due to the weight of the main unit 1 itself, and at this time, it is attached to the four corners of the room. If the shade 5 is positioned with its four corners aligned, the triangular protrusion 21 of the protruding edge 19 will fit into the corrugated groove 20 of the engagement peripheral surface 16 in this state, and the subsequent cord storage case 9 and mounting frame 8 will be connected to each other. rotation is prevented. Moreover, when the engaging peripheral edge 16 and the protruding edge 19 are engaged, the engaging end 16b fits into the groove 24',
The cord storage case 9 and the mounting frame 8 are accurately positioned without shifting in the horizontal direction. Therefore, the main unit 1 can be suspended with the shade 5 kept parallel to the side of the room. If the main unit 1 is lifted slightly upward, the corrugated groove 20 and the triangular protrusion 21 will be disengaged, and the mounting direction of the main unit 1 can be freely adjusted. When lowered, the attachment direction is maintained by the engagement between the triangular protrusion 21 and the corrugated groove 20, so that the attachment direction can be adjusted freely.

(f) Effects of the invention Therefore, according to the invention, the engaging peripheral edge of the mounting frame attached to the main unit and the protruding edge of the cord storage case that stores the unnecessary part of the cord can be hooked and engaged. The main unit can be hung in a predetermined direction. Furthermore, the mounting direction of the main unit is maintained without shifting due to the jagged parts provided on the engaging peripheral edge and the protruding edge, and the cord storage case and the mounting frame are kept level by fitting into the groove of the engaging end. Since it is securely positioned without shifting in the direction, the installation direction will not change easily even if it comes into contact with the main unit, and even an amateur can easily and reliably move the four corners of the main unit's shade to the four corners of the room. This allows the main unit to blend in with the room. Furthermore, the mounting frame and the cord storage case are not separated during packaging, so there is no risk of them being lost.
