Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a hanging lighting fixture whose cord length can be adjusted.

[Conventional technology]

FIG. 2 is a cross-sectional view of a conventional cord adjustment device for a hanging lighting fixture disclosed in, for example, Japanese Patent Laid-Open No. 195808/1983. In the figure, 21 is a cord, 22 is a cord case for storing the extra cord 21, 23 is a main body of the instrument with the cord case 21 installed on the top, and 24 is a cord 2
1 and inserted into the hole at the top of the cord case 21, and is used to clamp and clamp the cord 21.

FIG. 3 shows an example of the cord fastener 24. In the figure, 25 is an annular body through which the cord 21 is passed, 26 is a plurality of tongues connected to the annular body 25 in an annular manner, and 27 is a thick part provided at the end of the tongue 26. The cord fastener 24 is slidably inserted into a hole provided at the top of the cord case 22.

Next, the operation will be explained. When the cord clamping tool 24 is pulled up from the hole at the top of the cord case 22, the thick part 27 of the tongue piece 26 clamps and clamps the cord 1. Also, in this state, if the cord 21 is pushed into the hole at the top of the cord case 22, the tightening tool 24 will slide downward together with the cord 21.
The tightening of the cord 21 by the thick portion 27 is then released.

To hold the cord fastener 24 in this position, the cord 21
You can freely adjust the length.

[Problem to be solved by the invention]

Since the conventional cord adjustment device for a hanging lighting fixture has the above-described structure, when adjusting the thickness of the cord, the cord adjustment device must always be adjusted from above the fixture body. For this reason, a work space is required between the ceiling and the cord case, and there is a limit to how short the cord can be made. In addition, when the main body of the device is large, even if there is sufficient work space, the user cannot reach the cord adjustment part with his/her hand, so it is not possible to shorten the cord and install the main body of the device close to the ceiling.

This invention was made to solve the above-mentioned problems, and even if there is no work space between the ceiling and the cord case, and even if the appliance itself is large, it can be installed close to the ceiling. The purpose is to obtain a hanging lighting fixture that can be used.

[Means to solve the problem]

The hanging lighting device according to the present invention includes a cord storage section with an opening at the bottom for storing an excess cord in the center of the device body, and a cord for hanging the device body in the cord storage section. It is equipped with a cord fastener to secure it to the

(Function) In the hanging lighting fixture according to the present invention, the length of the cord can be adjusted from the underside of the fixture body. therefore,
The appliance itself can be hung sufficiently close to the ceiling.

C Example] An embodiment of the present invention will be described below with reference to FIG.

In the figure, 1 is a cord, 2 is a fixture for attaching cord 1 to the ceiling, 3 is the appliance body, and 4 is a cord storage part with an opening at the bottom provided in the center of the appliance body 3 to store excess cords. 5 is the instrument body 3 with code 1
This is a cord fastening tool for fixing the cord to the instrument body 3, and is composed of a cord insertion tube 6 inserted into a hole in the center of the instrument body 3 and fixed therein, and a restriction nut 7 screwed into the male threaded portion of the cord insertion tube 6.

In the cord insertion j16, 8 is a cylindrical body, and 9.9 is a pair of left and right flexible tongue pieces, which are shaped like a part of the cylindrical body 8 cut long in the ring direction, and a thick part 10 at the tip. is provided. Reference numeral 11 denotes a male screw provided on the outer periphery of the cylindrical body 8.

In the drawing nut 7, 12 has an inner circumferential surface that is connected to the flexible tongue piece 9.
．． This is a conical constriction opening toward the 9 side.

Since the lighting fixture of the embodiment has the above-described configuration, when the fixture main body 3 is moved up and down from the bottom side, its position on the cord is determined. When you insert your hand into the cord storage part 4 from below and rotate the squeeze nut 7 in the forward direction, the flexible tongues 9, 9 of the cord insertion tube 6 are squeezed by the squeeze part 12, and the thick part 10 at the tip is inserted into the cord 1. to hold. When clamped, the instrument body 3 is fixed to the cord 1 in that position.

Conversely, when the restricting nut 7 is reversed, the restricting of the flexible tongue piece 9.9 by the restricting portion 12 is released, and the position of the instrument body 3 on the cord 1 can be arbitrarily varied.

(Problems to be Solved by the Invention) As explained above, according to the present invention, the cord fastener is provided in the cord storage part provided in the instrument body and whose lower side is open. The length of the cord can be adjusted on the side, thus allowing the appliance body to be mounted closer to the ceiling.
