JPH03214594A - Automatic driving device for cord switch of electric lamp - Google Patents

Abstract

PURPOSE:To provide a cord switch auto-driving device, which can be mounted on an electric lamp easily and operated automatically, by installing the cord switch driving part having a motor, power transmitting part, and takeup part in a position near the body of electric lamp, and connecting a control part separately from the driving part. CONSTITUTION:A cord switch driving part 1 is equipped with a motor 11, power transmitting part 12, takeup part 13 for cord 6, and power supply 14, and is provided with a control part 2 connected by an electric cord 5 to transmit signal so as to locate remotely. When a signal to connect the motor 11 with power supply 14 is sent from this control part 2 to the driving part 1 to operate the motor 11 for a certain time, the cord takeup part 13 is driven through the power transmitting part 12 to perform taking-up of the cord, and subsequent pulling-down actuates a switch 3. When lighting or putting-off of the light 4 is finished, the control part 2 gives a signal to operate subsequently the motor 11 is reverse direction for returning the cord 6 to its original position, and thus lighting or putting-off of the electric lamp is finished. This facilitates installation and provides automatic operation of lighting or putting-off.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an automatic light string switch drive Vill that automatically turns on and off the light.

[Prior Art] Conventionally, electric lights equipped with general string switches have been turned on and off as necessary by manually pulling down a string attached to the switch.

[Problems to be Solved by the Invention] In electric lights equipped with such a string switch, when necessary, for example, when adjusting the brightness, or when the person is far from the electric lamp, it is possible to I had to go up there and operate it.

For this reason, it has not been easy for ordinary people to attach timers, automatic operating devices, etc. to electric lamps. Also,
There were many cases where people forgot to turn off the lights, and the electricity bill increased considerably.

The present invention was made in view of the above-mentioned conventional problems, and provides a string switch that can be easily attached to a lamp equipped with a string switch and that can be automatically operated as necessary. The purpose is to provide an automatic drive device.

[Means for Solving a Problem] In order to achieve the above object, the electric light string switch automatic driving device of the present invention provides a lamp equipped with a string switch, which uses a motor and a power transmission to operate the string switch. A driving part of a string switch having a winding section and a winding part is provided in close proximity to the lamp body, and a control part for setting the lamp to turn on and off at an arbitrary time is connected to the driving part at a distance. It is characterized by being prepared by:

Further, the control unit is characterized in that it includes a clock having functions such as a timer and an alarm.

Furthermore, the control section is characterized in that it includes a light sensor that detects surrounding brightness and darkness to turn on and off the light.

[Function 1] In the automatic light string switch drive device as described above, when a lighting signal from the control section is sent to the string switch drive section,
The motor rotates and drives the winding section via the power transmission section to wind up the string connected to the switch by an amount that turns on the switch. Then, once the light is on, the motor is immediately rotated in the reverse direction by a signal from the control unit.
Wind the string back to its original state. In the case of turning off the light, a light-off signal is sent to the drive section by operation of the control section, which rotates the motor, winds the switch string around the winding section as in the case of turning on the light, operates the switch, and turns off the light.

The control unit may be operated by automatically sending a signal to the drive unit when a time set by a timer has elapsed.

Furthermore, if a light sensor is incorporated in the control section, a signal to turn on or off the light can be sent to the drive section depending on the surrounding brightness or darkness. Of course, if the control section is equipped with an alarm, it is also possible to send a signal to the drive section by manual operation.

[Example] Examples will be described with reference to the drawings.

In the electric light string switch automatic driving device according to the present invention, as shown in FIG. If possible, the drive unit 1 is attached to the lower part of the lamp integrally with the lamp body 8 or close to it with a locking member, etc.
is installed. As shown in FIG. 2, the drive section 1 includes a motor 11, a power transmission section 12 that combines a bevel gear that transmits the rotation of the motor, a winding section 13 for the string 6, and a power source that serves as a driving source for the seventh gear 11. It is equipped with 14. The drive unit 1 is provided with a control unit 2 located remotely and connected to it by a cord 5 that transmits signals, and the drive of the motor 11 pulls the string 6 of the string switch 3 to turn on or off the light. Control can be performed so that the operation is returned immediately after it is finished. A timer display section 21 and a time setting operation element 22 are attached to the control section 2, and the time for turning on and off the light can be set, and the time can also be displayed on the display section 21.

In the electric light string switch automatic drive device having the above configuration, when the time set in the timer of the control unit 2 for turning on or off the light is reached, a signal to connect the motor 11 of the drive unit 1 and the power source 14 is activated from the control unit 2. Motor 11
Rotate for a predetermined amount of time. This rotation is caused by the power transmission part 1
2 to drive the winding section 13 of the string 6 to wind it up;
Pull it down and operate switch 3. When the light 4 is turned on or off, the control unit 2 sends a signal to continue to reversely rotate the motor 11 and return the string 6 to its original state, thereby completing the operation of turning on or off the light.

The control unit 2 with the above configuration further incorporates an alarm,
The set time may be displayed by sound.

Furthermore, a light sensor may be incorporated into the control section 2 to sense the brightness and darkness of the surroundings and send an activation signal to the drive section 1.

Further, the drive unit 1 is attached to the lamp body 8 in a convenient position for pulling down the string 6 of the string switch 3 below the main body using a locking member, etc. If there is, there is no need to use a locking member to attach it all together, and if you pull down the cord 5 in this state, the string 6 will be pulled down together with the drive unit 1 as in the past, allowing you to directly operate the string switch 3. It is also possible to make it possible.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

The automatic string switch drive device for electric lights with the above configuration can be installed in electric lights equipped with a string switch, since it is only necessary to provide the driving section of the string switch, which consists of a motor, a power transmission section, and a winding section, close to the lamp body. Since the control unit for setting the light to turn on and off at any time is connected remotely to the drive unit, it is possible to easily approach the light body and
This eliminates the troublesome effort of pulling strings, and has the excellent effect of automatically turning on or off the lights at a set time.

Furthermore, since the control section can be provided with various functions, it has the excellent effect of being able to easily turn on or off a general electric light automatically depending on the purpose.
