Description

[Detailed description of the invention]

[0001]

This invention is applied to an existing wall switch and turns on and off the switch after a predetermined time has elapsed.
The present invention relates to a wall switch timer for FF.

2. Description of the Related Art In general households, power is often wasted due to forgetting to turn off electricity. Particularly noticeable are the cases of forgetting to turn off the lighting of the toilet, the entrance lights, the corridor stairs, and leaving the ventilation fans on. On the other hand, in many electric appliances, a timer is provided in the electric appliance, and a switch is automatically turned on and off when a desired time is reached by setting and resetting the timer.

[0003]

[Problems to be solved by the invention] However, although there are timers provided for individual electric appliances, when it is intended to add a timer function to a wall switch used for lighting of an existing house or the like, It cannot be easily implemented because the entire switch needs to be replaced or associated work is involved. Also, this kind of renovation is basically not possible, especially in rental housing.

This invention solves the above problem.
It is attached as an attachment to an existing wall switch, and this switch is turned on according to the set time of the timer.
It is an object of the present invention to provide a wall switch timer that can be turned off in N and OFF.

[0005]

In order to achieve the above object, the present invention provides a case which is fixed to a peripheral edge of a panel of a wall switch, a timer body which is built in the case, and which protrudes from a surface of the case. ON of the set timer, the reset switch, and the wall switch, which protrudes from the timer body alternately so as to be able to protrude and retract from the timer main body in conjunction with the setting operation, time-up operation, and pressing operation of the reset switch of the timer set dial.
And a pair of actuators facing each other on the side and the OFF side.

[0006]

The wall switch can be provided with a timer function by fixing the case to the peripheral edge of the panel of the wall switch. By the setting operation of the timer set dial, the time-up operation, and the pressing operation of the reset switch, the respective actuators alternately come and go, and press the ON or OFF side of the wall switch to turn the switch ON or OFF.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. 1 and 2, a wall switch timer 1 includes a rectangular case 3 fitted and fixed to a peripheral edge of a switch panel 2a of an existing wall switch 2, a timer body 4 built in the case 3, A timer set dial 5 protruding from the surface of the case 3 and a reset switch 6 formed in a shape similar to that of the switch 2; a pair of actuators 7 protruding from the timer main body 4 so as to be able to come and go; Is attached to the switch panel 2a.

The wall switch 2 is a standard type toggle switch used in ordinary households, and its dimensions and the dimensions of the panel 2a are determined. The mounting bracket 8 and the case 3 are accordingly determined. Is determined. Then, the case 3 is connected to the panel 2 via the mounting bracket 8.
When fixed around "a", each actuator 7 is positioned so as to face the ON side and the OFF side, which are both swing ends of the switch 2.

On the other hand, the timer body 4 is a timer set
In conjunction with dial 5 set operation and time-up operation
To make the pair of actuators 7 appear and disappear alternately.
ing. That is, the timer set dial 5 rotates
The pair of actuators 7 directly
Since the linear motion is used, the rotary motion
Uses well-known technology for exercise.

Accordingly, for example, as shown in FIG. 3A, with the timer set dial 5 set, one actuator 7 facing one side of the switch 2 projects, and the other actuator 7 retracts. In this state, the switch 2 is in the ON state, and the lighting equipment (not shown) connected to the switch 2 is turned on. When the set time elapses from this point and the time is up, that is, when the timer set dial 5 is rotated to the position of the scale 0, the other actuator 7 projects as shown in FIG. When the switch 2 is immersed, the switch 2 is pressed to the opposite side and turned to the OFF side. This turns off the lighting equipment. That is, in this example, the present invention can be applied to applications such as automatically turning off the light after a predetermined time has elapsed after setting and turning off other electric appliances connected to the wall switch 2.

On the other hand, when the reset switch 6 is pressed,
For example, each of the actuators is
It is possible to make 7 appear alternately from the current state to the opposite state
When the timer is timed up as shown in FIG. 3B and the lighting fixture is turned on from a state in which the lighting fixture has been turned off, for example, if the reset switch 6 is pressed, the resetting is performed as shown in FIG.
As shown in (a), the switch 2 is turned on by alternately protruding and retracting the actuator 7, and the lighting equipment is turned on. To turn off the light, the reset switch 6 is pressed again to turn off the switch 2 by the same operation.

In the embodiment, the timer 1 for the wall switch is used.
Was applied to the case of a single wall switch, but the size and shape of the case 3, the mounting bracket 8, and the timer were adjusted to the standard dimensions according to the existing double switch or the combination of the switch and the outlet. Combinations with functions can be provided.

[0013]

As described in detail in the above embodiments, in the wall switch timer according to the present invention,
It can be easily attached to an existing wall switch, and automatically turns on and off electric appliances such as lighting connected to the wall switch after a lapse of time set by a timer set dial. Therefore, the timer function can be provided without changing the existing wall switch to the one with the timer, and it can be implemented at low cost.
