Description

[Detailed description of the invention] The present invention relates to a hanging device for lighting equipment.

In a conventional hanging type lighting fixture, as shown in FIG. 1, an enlarged portion 7 is formed at the end of the external braid 5 of the round cord 4, and a cross-sectional path fL-shape has a round cord insertion hole 8 in the center. A presser metal fitting 9 of the shape is fitted upwardly onto the rounded cord 4, the enlarged part 7 is locked to the lower surface of the periphery of the rounded cord insertion hole 8, and the core cord of the rounded cord 4 is wired to the two-piece socket 11. A two-piece socket 11 is screwed to the end of a presser metal fitting 9 via a glove holder 10, a glove 12, a wooden cover 13 and a light bulb 14 are arranged, and the lighting equipment is suspended from the lower part of the round cord 4.

However, in such a conventional example, in order to lock the ampullae and the presser metal fitting, it is necessary to have a metal fitting that expands the ampullae outward so that the ampullatic portion does not slip out of the round cord insertion hole, and a presser metal fitting. The disadvantage is that it is difficult to reduce the distance between the screw holes at both ends of the presser fitting due to the selection and the enlarged portion.
The pitch of the threaded holes of the one-piece socket is smaller than the pitch of the threaded holes of the two-piece socket, so the pitch of the threaded holes of the presser fitting cannot be matched to the pitch of the threaded holes of the one-piece socket, This also has the disadvantage that it is not possible to use an inexpensive one-piece socket, and furthermore, since the presser fitting is only locked to the ampulla, the lighting fixture rotates, and the core cord of the round cord is rotated due to the rotation of the lighting fixture. There was a risk that the part where the core cord and socket terminal were soldered would come off due to twisting.

The present invention was made in view of the drawbacks of the conventional slanted cord, and its purpose is to simplify the connection between the external braid of the round cord and the lighting fixture, reduce costs, and reduce the rotation of the lighting fixture. An object of the present invention is to provide a hanging device for a lighting fixture that can prevent the hanging of lighting equipment.

The present invention will be explained in detail below.

The hanging device for lighting equipment of the present invention has a core cord insertion hole 15 formed approximately in the center of a hanging metal fitting 2 in the form of a long and thin plate, and screw holes 1 are provided at both ends of the hanging metal fitting 2 in the longitudinal direction. A claw 3 protruding outward is provided approximately in the longitudinal center of the side edge parallel to the longitudinal direction of the hanging bracket 2, and the external braid at the lower end of the round cord 4 arranged in the vertical direction is turned over. The core cord 17 is inserted into the core cord insertion hole 15 of the hanging metal fitting 2, and the external braid 5 of the rounded cord 4 is entwined with the claw 3 at approximately the longitudinal center of the hanging metal fitting 2, and wound in the transverse direction. Turn the hanging metal fitting 2 to fix it, touch the hanging metal fitting 2 to the top surface of the socket 6, screw the socket set screw 19 into the threaded hole 1 of the hanging metal fitting 2 from the socket 6, and screw the socket 6. It has been stopped.

Next, the present invention will be specifically explained using examples.

As shown in FIG. 2, the socket 6 is screwed through the globe holder 10 to the hanging metal fitting 2 fixed to the lower end of the external braid 5 of the round cord 4, and the bulb 14 is fitted into the socket 6. A globe 12 is attached to the lamp, and the hanging fitting 2 and the glove holder 10 are covered with a wooden cover 13 to form a lighting fixture.

FIG. 3 shows a hanging fitting 2, which has a core cord insertion hole 15 bored in the center of an elongated plate material having an oval shape, and screw holes 1 provided at both ends in the long diameter direction. The pitch D of the socket 6 is the pitch D of the screw hole 16 of the socket 6.
In addition, a claw 3 protrudes outward from the side edge in the short diameter direction of the hanging fitting 2.The end of the round cord 4 has the external braid 5 stripped off, as shown in Figure 4. As shown, insert the core cord 17 at the end of the rounded cord 4 with the external braid 5 turned over into the core cord insertion hole 15, and insert the end of the external braid 5 into the claw 3.
The external braid 5 is fixed to the hanging metal fitting 2 by winding it in the short diameter direction of the hanging metal fitting 2 while intertwining with the external braid 5.

After that, attach the end of the core cord 17 to the glove holder 1.
0 through the through hole 18, and the end of the core cord 17 is inserted into the socket 6.
The socket set screw 19 is passed from below through the screw hole 16 of the socket 6 and the glove holder 100 hole, and then screwed into the screw hole 1 of the hanging fitting 2.

As a result, the jig globe holder 10 and the socket 6 are suspended from the lower end of the round cord 4.

Further, a light bulb 14 is placed in the socket 6, a glove 12 is screwed onto the glove holder 10, a round cord 4 is passed through the tube part 13a of the wooden cover 13, and the hanging fitting 2 and the glove holder 10 are covered with the wooden cover 13. be.

In the hanging device for lighting equipment of the present invention, as described above, the end of the external braid of the round cord is fixed to the hanging metal fitting, and the socket is screwed into the screw hole of the hanging metal fitting. , unlike the conventional method, there is no need for a bulk part at the end of the external braid of the round cord, and therefore the pitch of the screw hole for screwing the socket to the hanging bracket is no longer limited by the bulk part, and the pitch of the screw hole can be reduced. It is possible to use a one-piece socket with a small pitch of threaded holes instead of being limited to a two-piece socket, reducing costs, and only a hanging metal fitting is needed to connect the round cord and socket. Unlike the conventional method, two metal fittings such as a metal fitting for expanding the ampulla outward and a holding metal fitting are not required, and the number of parts can be reduced and costs can be reduced.

Furthermore, the round cord is entwined with the claw and fixed to the hanging metal fitting, and the socket is screwed to the hanging metal fitting, so the round cord and the socket do not rotate with respect to each other, and therefore the round cord The soldering of the core cord and socket should be such that there is no risk of the core cord twisting when the core cord rotates with respect to the socket, and the lower part of the external braid should be entwined with the nails, and the core cord should be twisted in the short direction of the hanging bracket. Since it is wound, the lower part of the external braid can be fixed with a claw simply by winding it, and the hanging bracket can be attached to the lower part of the external braid.Furthermore, the hanging bracket can be attached to the top surface of the socket. Since the socket is screwed in place by screwing the socket set screw into the screw hole of the hanging metal fitting from the socket, the external braid wrapped around the hanging metal fitting is firmly clamped between the hanging metal fitting and the socket. The socket and hanging metal fittings are further firmly fixed to the external braid.
