Description

[Detailed description of the invention] Industrial applications The present invention relates to a hanging lighting fixture suspended by a wire.

Conventional structure and its problems Conventionally, in a hanging lighting fixture suspended by a wire, the wire and fixture were connected by connecting the wire to an inverted T-shaped fitting attached to the top of the fixture's main body chassis using screws, etc. It was meant to connect. However, since the curled cord wrapped around the wire for power supply passes near the metal fitting,
The curl cord is likely to rub against the metal fittings, causing damage to the sheath. To prevent this, the curl cord is inserted through the cylindrical body that houses the wire and the lower end of the curl cord so that it can pass toward the side. A hole is provided, and the curl cord passing through the insertion hole is configured to move as far away from the metal fitting as possible. However, forming the above-mentioned insertion hole requires filling the parts other than the insertion hole when forming the cylinder (however, a wire insertion hole is required in the center for the wire to pass through). Problems arise in that the structure of the cylinder becomes complicated and the material cost increases.

OBJECTS OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a hanging lighting fixture that can completely protect the curl cord and simplify the cylindrical body. be.

Structure of the Invention In order to achieve the above-mentioned objects, the present invention includes a main body chassis in which a downwardly facing cut-and-raised piece is formed, and a main body chassis that is connected to the cut-and-raised piece through a hole formed by forming the cut-and-raised piece. A wire, a curl cord wound around the wire and introduced into the lower surface of the main body chassis through the hole, and a cylindrical body attached to the upper surface of the main body chassis and housing the lower ends of the wire and the curl cord. DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

A metal main body chassis 1 has a downward cut-and-raised piece 2 formed in the center, and a hole 3 is formed by the cut-and-raised piece 2. The wire 4 passes through the hole 3 and cuts out the cut piece 2.
is combined with This coupling means, for example, provides a knot at the lower end of the wire 4, fastens the wire 4 with an end fitting 6 having a hole 6, and inserts a screw 8 into the hole 6 through a washer. This is done by screwing the The curl cord 10 is wound around the wire 4 and introduced into the lower surface of the main body chassis 1 through the hole 3 (not shown). The metal cylindrical body 11 has a collar piece 12 formed at its lower end, for example, and is attached to the upper surface of the main body chassis 1 by screwing a screw 13 through the collar piece 12 and into a hole 15 in the main body 7 beam 1. The wire 4 and the lower end of the curl cord 1o are stored therein. A support fitting 1T is attached to the lower surface of the main body chassis 1 using KU screws 16, and
7 supports the socket 19 with screws 18.

A drawstring 20 is pulled out from both sides of the socket 19, and a puller 21 made of a substantially U-shaped metal wire is connected to the end thereof. The lower center of the pull handle 21 has protruding parts with narrow intervals, the lower end of which is pulled out from the hole 23 of the glove 22. The lamp 24 is attached to the socket 19,
By operating the puller 21, the lamp 24 can be turned on and off using a switch inside the socket 19. The hole edge 26 of the large diameter hole 25 on the top surface of the globe 22 is connected to the main body chassis 1.
It is attached to the main body chassis 1 by being placed on the top surface of both ends of the main body chassis 1. At the time of installation, the main body chassis 1 is tilted and then inserted into the hole 25, and when it is made horizontal again, the hole edges 26 are placed on the upper surface of both ends of the main body chassis 10, and the installation is completed.

The upper cover 27 is placed on the upper surface of the globe 22 , and the center of the upper surface is fitted onto the outer periphery of the cylinder 11 .
It is fixed by screwing a nut 28 onto the upper edge of 1.

As described above, the lower end of the curl cord 1o enters the lower surface of the main body chassis 1 through the hole 3 and is connected to the socket 19 (not shown). Further, the upper end of the wire 4 is attached to the ceiling surface or to an elevator attached to the ceiling surface.

Effects of the Invention According to the present invention having the configuration described above, the following effects can be achieved.

1. Since the cut and raised pieces to which the wires are connected are facing downward, it is difficult for the curl cord to touch the lower edge or side edge of the cut and raised pieces, and even if it does, the downward force due to the curl cord's own weight will not be applied to the cut and raised pieces. It faces away from debris, ensuring complete protection of the curl cord. Damage to the curl cord is likely to occur when the instrument is shaken or by shaking accompanying the lifting and lowering of the instrument, but in the present invention it has been found that the damage to the curl cord is far less than in the conventional example.

2. And, due to less damage to the curl cord,
There is no need to provide an insertion hole exclusively for the curl cord in the cylinder to restrict the passage of the curl cord, the structure of the cylinder is simplified, and it can be manufactured at low cost.

3. The cut-and-raised piece is formed integrally with the main body chassis, making it easy to manufacture.Furthermore, since the cut-out piece faces downward rather than upward, which would fit into the cylindrical body, a sufficient width can be taken, allowing the instrument to be This is particularly useful in cases where there is a high possibility that a fairly large load will be applied momentarily, such as with an elevating type lighting fixture.

4. Since the main body chassis with the cut and raised piece and the cylinder body are attached, the wire connected to the cut and raised piece has good centering performance in the cylinder body, and friction between the wire and the curl cord is possible. It is useful for protecting curl cords.
