[The problem that the idea attempts to solve]

However, in such a hanging type lighting fixture, the nut 13 is fitted onto the curled cord 22, so it needs to have a large diameter, and the curled cord 22 is visible by its spiral diameter, both of which are very large. In some cases, the curl cord 22 is noticeable and may be inconvenient in terms of appearance.
When the lamp expands and contracts, the hanging lighting fixture body 6 may rotate due to the curling tendency of the curl cord 22, and in lighting fixtures with a rectangular shade 11, the direction of the shade 11 and the room may change, resulting in an unsightly appearance. There was a problem.

The present invention was devised in view of these conventional problems, and its purpose is to provide a hanging type lighting fixture in which the power cord is less noticeable and does not rotate even when raised or lowered.

[Means to solve the problem]

In the hanging type lighting equipment according to the present invention, the main body of the lighting equipment is suspended from a mounting surface using a hanging wire led out from an elevator so that the lighting equipment can be raised and lowered, and the hanging wire is extended for a length longer than the maximum distance from the mounting surface to the main body of the lighting equipment. Connecting the lighting equipment main body to a power source with a power cord that has been adjusted, movably inserting a cord stopper that locks the power cord into the hanging wire, and twisting the power cord above the cord stopper to draw a circle; Each of the cord fasteners has a substantially cylindrical shape, and a power cord insertion part and a hanging wire insertion part, which are arranged in parallel with each other, are divided into two parts along a plane substantially along the axial direction, and are connected by a hinge part, and a part opposite to the hinge part. The side split parts are made of elastic plastic so that they can be engaged and fixed with each other, and the cross section of the power cord is approximately oval, and the power cord is bent in the short axis direction of the approximately oval cross section to draw a circle in the vertical direction. It is.

[Effect]

According to the present invention, the power supply wire has a substantially oval cross-sectional shape, and the excess portion forms a circle above the cord stopper, allowing the lighting equipment to be raised and lowered by an elevator without using a curl cord. At the same time, the lighting fixture body does not rotate due to the curled cord, giving it a clean appearance.
There is no need to connect the power cord to a curled cord in the middle, no closed end connector is required, and the cord stopper is made of one piece, reducing the number of parts.The lighting equipment body and elevator are connected with a hanging wire. After that, the cord stopper can be attached to the hanging wire and power cord, making it easy to assemble the lighting fixture and reducing the number of assembly steps.

〔Example〕

1 to 4 show one embodiment of the present invention, which will be explained below based on the drawings.

As shown in FIGS. 1 and 2, a mounting bracket 2 is fixed to a mounting surface 1 such as a ceiling with wood screws 3, and an elevator 4 is locked to the mounting bracket 2 and suspended, almost in the same manner as the conventional example. , a lighting fixture main body 6 is suspended from the lower end of a hanging wire 5 led out from the elevator 4, and the hanging wire 5 is wound around the elevator 4 and the lighting fixture main body 6 in an unloaded state.
In the suspended state, it is pulled out from the elevator 4 and maintained at an arbitrary length.

The lighting fixture main body 6 has a plurality of sockets 7 on its side, each of which is fitted with an incandescent lamp 8, and a handle 9 for raising and lowering the lighting fixture is protruded from its lower end, as well as a switch for switching the lamp 8 on and off. One example of the drawstring is suspended, and a shade receiver 61 on which the shade 11 is placed is formed at the upper end.

The elevator 4 is covered with a cover 12 that is fitted onto a threaded portion 42 formed around a hanging wire outlet 41 at the lower end. The cover 12 is pushed up by a nut 13 screwed into the threaded portion 42 and comes into contact with the mounting surface.

On the mounting surface 1, a hanging ceiling body 14 is attached with a wood screw 1 at a distance from the mounting position of the elevator 4.
A power cord 17 having a substantially elliptical cross section as shown in FIG.
A hook ceiling cover 18 fitted onto the outside covers the hook ceiling body 14 and the hook ceiling cap 16.

After the power cord 17 is introduced into the cover 12, it is guided out of the cover 12 along the side surface of the threaded part 42 of the elevator 4, inserted into the nut 13 together with the hanging wire 5, and then connected to the lighting equipment main body 6. It is introduced into the interior and connected to lighting electrical parts such as a socket 7 and a switch, and then connected to a power source. Further, the power cord 17 has a length corresponding to the maximum distance between the elevator 4 and the lighting device main body 6 so as to be able to adapt to changes in the length of the hanging wire 5 as the lighting device main body 6 goes up and down. At the same time, the cord is twisted to form a loop on the upper side by a cord stopper 19 and is fastened to the hanging wire 5.

As shown in FIG. 3, the cord stopper 19 is made of elastic plastic, and consists of a hinge portion 191 that is symmetrically divided into two large and small cylinders arranged in series.
The split portion on the opposite side of the hinge portion 191 is connected by an engaging piece 192 and an engaging protrusion 193, and the approximately semi-cylindrical power cord insertion portions 194, 194' and the power cord Inset part 194,
Approximately semi-cylindrical hanging wire insertion portions 195 and 195' having a smaller diameter than 194' are provided in succession.

When fixing the power cord 17 to the hanging wire 5 with the cord stopper 19, simultaneously insert the power cord 17 into one power cord insertion part 194,
The hanging wire 5 is positioned in one of the hanging wire insertion parts 195, and then folded back from the hinge part 191, the engaging piece 192 is engaged with the engaging protrusion 193, and the cord stopper 19 is moved relative to the hanging wire 5. It is made flexible and is locked to the power cord 17. The cord stopper 19 is fixed to the hanging wire 5 and is attached to the elevator 4 of the hanging wire 5.
It is placed on a stopper 20' fixed to the suspension wire 5 below the stopper 20 which determines the minimum length of the wire.

As shown in FIG. 2, the power cord 17 has a roughly elliptical cross-sectional shape and is twisted, so that the excess area above the cord stopper 19 forms a circle, which prevents the lighting fixture body 6 from moving up and down. Accordingly, the cord stop 19 moves up and down along the hanging wire 5 and is locked by friction due to the allowance of the power cord 17 below the cord stop 19, and the size of this circle increases and decreases.

Note that the elevator 4 may be disposed on the lighting fixture body 6 instead of being attached to the mounting surface 1.

This hanging type lighting fixture is constructed as described above, and the power supply wire 17 has a substantially elliptical cross-sectional shape, with the excess portion forming a circle above the cord stopper 19, and the curled cord 22 is The lighting fixture body 6 can be raised and lowered by the elevator 4 without being used, and the lighting fixture body 6 does not rotate due to the curled cord 22, resulting in a clean appearance and the power cord 17 can be curled in the middle. There is no need to connect to the cord 22, the closed end connector 21 is unnecessary, and the cord stopper 19 is also composed of one part, reducing the number of parts, and the lighting equipment main body 6 and the elevator 4 are connected with the hanging wire 5. After that, the cord stopper 19 can be attached to the hanging wire 5 and the power cord 17, so that the lighting equipment can be easily assembled and the number of assembly steps can be reduced.

[Effect of idea]

Since the present invention is constructed as described above, the cross-sectional shape of the power supply wire is approximately oval, and the excess portion forms a circle above the cord stopper. This allows the lighting fixture body to be raised and lowered, and the lighting fixture body does not rotate due to the curled cord, resulting in a clean appearance. There is no need to connect the power cord to the curled cord in the middle, and the closed end connector eliminates the need to connect the power cord to the curled cord. In addition, the cord stopper is composed of one part, which reduces the number of parts, and the cord stopper can be attached to the hanging wire and the power cord after connecting the lighting equipment main body 6 and the elevator with the hanging wire 5. This makes it easy to assemble the lighting equipment and reduces assembly man-hours.
