Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) The present invention relates to a ceiling-suspended lighting fixture.

(Prior Art) Conventionally, as shown in Fig. 1, a ceiling-suspended lighting fixture has been constructed by connecting a socket 3 with a built-in switch to a cord 2 hanging from a rosette 1 on the ceiling. A lamp 4 is attached to the socket 3, and a switch tension string 6 is led out from the side of the socket 3, and an operating string 7 such as a ball chain is connected to this switch tension string 6.

However, according to such a structure, the operation string 7
When pulling the button to make the lamp 4 flash, the socket 3 is pulled to one side, causing the entire unit to shake significantly, and the operation string 7 comes into contact with the lamp 4, which makes it uncomfortable to hold, and there is a risk that the lamp 4 may be damaged. There is also.

Therefore, in order to solve this problem, conventionally, as shown in Fig. 2, a support frame 8 is provided on a socket 3 that is suspended from a ceiling rosette 1 via a cord 2, and a switch is attached to this support frame 8. A coil spring 9 is attached at the opposite position facing the tension string 6, and the upper ends of suspension strings 10 such as ball chains are connected to the switch tension string 6 and the coil spring 9, respectively. It is proposed that the lower ends are connected by a connecting piece 11 and the operating rod 12 is suspended from the middle of this connecting piece 11.

However, this structure has the following problems. That is, although the switch tension string 6 tends to vary in length due to connections such as hand knotting, switch assembly processing, etc., the suspension string 10 is suspended from the switch tension string 6 in its stretched state. For,
It is difficult to adjust the lengths of the coil spring 9 and the hanging cord 10 on the opposite side in accordance with the lengths of the coil springs 9 and 10, and therefore the connecting piece 11 tends to be in an inclined state, resulting in poor appearance.

(Problems to be Solved by the Invention) As described above, in the conventional lighting equipment, it is difficult to adjust the length of the switch pull string led out from the side of the socket.

The present invention is an attempt to solve such problems, and aims to provide good operability without being affected by variations in the length of the switch tension cord, and to prevent the operating rod from tilting. That is.

[Structure of the idea]

(Means for Solving the Problems) The lighting equipment of the present invention includes a socket with a built-in switch that is suspended from the ceiling, and a support frame provided horizontally.
Coil springs are suspended from both ends of this support frame, and the lower ends of the coil springs at both ends support both ends of a substantially U-shaped operating rod, which hangs downward, and one end of this operating rod is attached to the side of the socket. The switch tension strings are connected by loosening them in the middle.

(Function) According to the present invention, when the operating rod is pulled down, this pulling force is applied equally to the left and right sides of the socket via the coil springs at both ends, and at the same time, the switch tension string is pulled and the switch is operated.

(Example) Hereinafter, an example of the present invention will be described with reference to FIG.

A socket 3 with a built-in switch is connected to a cord 2 suspended from the ceiling, a lamp 4 is attached to the socket 3, and a switch tension string 6 is led out from the side of the socket 3. Further, a horizontal support frame 8 is fixed to the outer periphery of the socket 3, and coil springs 13 having the same length and the same elastic modulus are attached and suspended at the relative positions of both ends of the support frame 8. Engagement portions 15 at both ends of an operating rod 14 made of a steel wire bent into a substantially U-shape are respectively engaged and supported by the lower end of the coil spring 13, and are suspended downward. Then, the operating rod 1
4 is formed in such a shape that opposing side pieces do not come into contact with the lamp 4. Further, the lower end of the switch tension cord 6 led out from the socket 3 is attached to one end of the operating rod 14 with the middle part thereof being loosened.
It is connected to 5.

Then, when the operating rod 14 is pulled down, the coil springs 13 at both ends, which are the same length and have the same elasticity, are pulled and extended to the same length, that is, the pulling force is applied equally to the left and right sides of the socket 3, and the operation is performed. The rod 14 does not tilt, and at the same time, the switch pull string 6 connected to one end of the operating rod 14 is pulled to perform the switch operation.

In the above embodiment, a steel wire bent into a U-shape is used as the operating rod 14, but a suspension string 10 such as a ball chain is attached to both ends of the rigid connecting piece 11 as shown in FIG. Concatenate and make the whole U
A letter-shaped one may also be used.

[Effect of idea]

According to the present invention, coil springs are suspended from both ends of a support frame in a socket with a built-in switch, and both ends of a U-shaped operating rod are suspended from the coil springs at both ends, and one end of this operating rod is suspended. By connecting the switch tension string derived from the socket to the socket, when the operating rod is pulled down, equal tension is applied to the left and right sides of the socket via the coil springs at both ends, preventing the socket from tilting or swinging. At the same time, the switch pull string connected to one end of the operating rod is pulled to operate the switch, so the entire lamp does not shake or damage the lamp when the switch is operated. In addition, by connecting the switch tension string to the operating lever with the middle part loosened, it is possible to absorb variations in length due to hand-tying the switch tension string or assembling the switch, and prevent the operating lever from tilting.
