Description

[Detailed description of the invention] The present invention is capable of controlling the energization of the electric appliance, such as an incandescent table light, by arbitrarily operating a tipping switch that cuts off the power to the electric appliance when it falls over during normal operation. This is about a switch that does this.

Conventionally, electric appliances such as incandescent lamps and table lights have been equipped with a tip-over switch that cuts off the power to the electric appliance when it falls over. The appliance switch is arbitrarily operated during normal operation to control the energization of the appliance, and when the appliance falls over, the overturning switch is operated to cut off the energization to the appliance.

With the above structure, an overturning switch and an instrument switch must be provided, which has the disadvantage of making the structure complicated and expensive.

The present invention relates to a switch that eliminates the above-mentioned drawbacks.

An embodiment of the switch of the present invention will be described below with reference to the drawings.

The switch of the present invention is provided with a pivot part 4 having a pivot hole 3, a holding recess 5, and a through hole 6 on the inside of the bottom plate 2 of the main body 1 of the electrical appliance such as an incandescent table light. A sliding hole 8 is provided in the top plate 7, and the pivot hole 10 of one end of the switch body 9 is aligned with the pivot hole 3 of the pivot portion 4, and the pivot hole 3 of the pivot portion 4 and the pivot hole of the switch body 9 are aligned. A pivot screw 11 is inserted into the support hole 10, and the pivot screw 11 is attached with a nut 12 to pivot the other end of the switch main body 9 inside the bottom plate 2 of the main body 1. One end of the switch main body 9 is always urged toward the top plate 7 of the main body 1 in the holding recess 5 of the bottom plate 2 of the main body 1, so that the operating rod 13 at one end of the switch main body 9 is held in the holding recess 5 of the bottom plate 2 of the main body 1 as shown in FIG. A switch knob 16 holds a spring 14 positioned in the through hole 6 of the bottom plate 2 of the main body 1, and operates the switch main body 9 so that the knob 15 protrudes from the sliding hole 8 of the top plate 7 of the main body 1. The above body 1
It is configured to be slidably disposed between the top plate 7 and the bottom plate 2.

In the above-mentioned configuration, the switch body 9 performs a closing operation (energizing operation) when the operating rod 13 is pressed, and performs an opening operation (cutting operation) when the operating rod 13 is not pressed. Also, the pressing operation by sliding the switch knob 16 of the switch body 9 is performed by a rounded portion 1 on the outer circumferential upper surface of the other end of the switch body 9.
and a slope portion 18 which presses the curved portion 18 by being brought into contact with the curved portion 18 and slidably moved thereon.
9 is provided on the inside of the upper surface of the switch knob 16.

FIG. 4 is a circuit diagram using the switch of the present invention. In FIG. 4, 20 is the switch of the present invention, 21 is an AC power supply, and 22 is the switch 2 of the present invention.
An electric appliance whose energization is controlled by 0 is an incandescent lamp, for example, an incandescent table light.

Next, to explain how the switch constructed as described above is used, when the switch knob 16 is used to cut off the electricity, the switch knob 16 is slid as shown in FIG. The sloped part 19 of the switch 16 is prevented from coming into contact with the rounded part 18 of the switch body 9 so as not to be pressed by the sloped part 19 of the switch knob 16, and the other end of the switch body 9 is fixed to the top plate by the spring 14. 7 directions so that the operating rod 13 of the switch main body 9 is located in the through hole 6 of the bottom plate 2 of the main body 1, and the operating rod 1
The opening operation is performed by releasing the pressure on the bottom plate 2 of the main body 1 of No. 3 by a mounting body such as a desk on which it is placed, and cutting off the electricity to the electric appliance, and in FIG. 4, the incandescent lamp 22. When applying electricity using the switch knob 16, slide the switch knob 16 as shown in FIG.
9 is brought into contact with the rounded portion of the switch body 9 and pressed by the sloped portion 19 of the switch knob 16, and the other end of the switch body 9 is pressed against the biasing force of the spring 14 to push the bottom plate 2 of the main body 1. The operating rod 13 of the switch body 9 touches the bottom plate 2 of the main body 1.
The operating rod 13 is pressed by a mounting body such as a desk on which the bottom plate 2 of the main body 1 is placed to perform the closing operation, and the electrical appliance is energized. The incandescent lamp 22 is energized. At this time, if the electrical appliance falls on the mounting body, the pressure on the operating rod 13 of the switch body 9 by the mounting body such as a desk on which the bottom plate 2 of the main body 1 is placed is released, and the electrical appliance is energized. In FIG. 4, power to the incandescent lamp 22 is cut off.

In the switch of the present invention, when the switch knob is operated, the tipping switch is pushed toward the bottom of the electrical appliance against the bias of the biasing means, and the operating rod of the tipping switch is normally placed on the mounting body. Since the mounting body presses only when the device is pressed to control the power supply to the electric appliance, the power supply to the electric appliance can be reliably controlled using the tipping switch, and the configuration is simple and inexpensive. It can be done.
