Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a device for preventing people from forgetting to turn off the indoor lights in an office or the like after finishing work.

(Problems to be solved by conventional technology and ideas) When you turn off the indoor lights in an office etc. and go outside, the light switch is usually installed on the wall on the indoor side. When I close the door and go outside, I sometimes feel unsure whether the light is off or not.

To this end, it would be good to have a structure where the lights are turned off via a door switch when the door is closed and the person goes outside.However, if the door needs to be opened and closed frequently, the lights may be turned on and off each time. Since this happens, the door switch must be turned off, which may encourage people to forget to turn it off.

(Means for solving the problem) In contrast, with this invention, the light is normally turned on and off in conjunction with the door, and when the door switch is turned off, an indicator light is placed at an appropriate location near the door knob. This is to prevent people from forgetting to turn off the illumination light by making the lamp turn on.

(Example of the invention) An example of the invention will be explained with reference to the drawings.
FIG. 1 shows a wall surface on the indoor side, and an indicator light 4 and a changeover switch 5 are provided on the wall surface 1 at suitable locations near a knob 3 of a door 2. A door switch 6 is attached to the wall facing the outside of the room. When the door is opened outward, a door switch 6 is pulled to one side by the upper edge of the door 2 to alternately open and close the circuit. 7 is installed on the ceiling of the room. It is a lighting lamp.

As shown in Fig. 2, when the knob 3 is pulled to open the door 2 outward, the lower end of the tilt rod 8 is pushed against the upper edge of the door, causing it to rotate counterclockwise around its axis. The door switch 6 is a pull switch that is pulled by the upper end of the tilt rod 8 to alternately turn on and off the lighting lamp 7 connected to the circuit.
When the door 2 is opened from the outside and a person enters the room, the illumination lamp 7 is turned on, and when the door 2 is opened again and the person goes outside, the illumination lamp 7 is turned off.

Here, as mentioned above, if visitors come one after another or leave the room one by one, the illumination light 7 will be turned off and on each time, which is a problem, so in this case, the switching Switch 5 to the dotted line position in FIG. This changeover switch 5 has two switches 5a and 5b that operate simultaneously through a linkage, and as a result, the current from the power source does not pass through the door switch 6, but directly lights the illumination light 7 and indicator light 4. do.

In this way, when the person who finally leaves the room returns the selector switch 5 to the solid line position shown in FIG. .

(Effects of the invention) As described above, with this invention, the illumination light 7 is turned on and off via the door switch 6, so there is no risk of forgetting to turn it off, and when the door switch 6 is not used, the indicator light 4 is turned on. It is extremely efficient, as it alerts people to the problem and prevents mistakes.

Claims (1)

[Scope of utility model registration request] The indoor illumination light 7 is turned on and off via a door switch 6 which alternately opens and closes the circuit in response to opening of the door 2 leading into the room, and a changeover switch 5 which short-circuits the circuit of this door switch 6 at any time and in response to a short circuit. This device prevents the user from forgetting to turn off an indoor lighting light by disposing an indicator light 4 that lights up at a suitable location on the indoor wall near the knob 3 of the door 2.
