Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric switching device that enables both a switch operation by a drawstring and a switch operation without a drawstring in a lighting device that switches a switch by a drawstring. Many lighting fixtures hung on the ceiling in the room adopt a method of switching a switch with a pull cord. In the case of this method, a pulling string is attached to almost the center of the lighting fixture, and when the switch is operated, it is naturally necessary to pull the string at the substantially center of the lighting fixture to perform the switch operation. When it is desired to switch the switch without getting up from the floor, such as when sleeping, a long string has been replaced. However, the switch operation cannot be performed simply by lengthening the string at a place separated from the lighting device with the string by a certain amount or more. Therefore, it is necessary to move the body near the lighting equipment. This is
It is very inconvenient for people with disabilities.
The present invention is a switch switching device for a lighting device that compensates for this drawback so that remote control can be performed at a place with a long distance, and that a switch can be operated by a drawstring in the vicinity of the lighting device as in the conventional case. . Next, an embodiment of the present invention will be described with reference to the drawings. "Figure 1" is

(Refer to the electric circuit diagram of "FIG. 13"). Motor (2
The pinion (26) is press-fitted into the output shaft of 5), and the gear A
Power is transmitted to (27). Gear B (28) is gear A
(27) is integrally formed and meshes with a rack (30) formed on the operating shaft (8). Gear shaft (3
A groove recess is formed on the outer periphery of the cam (29) inserted into and supported by 6). Moving contact A (32) and contact a (3
3), the contact piece B (34) and the contact b (35) constitute a cam switch section (37) which is turned on and off by the rotation of the cam. Under normal conditions, the working shaft (8)

9 is pulled upward in the arrow direction by the restoring force (see FIG. 1) of the extension coil spring (31) and the changeover switch (2) in the lighting fixture (1) as shown in FIG. At this time, the cam switch part (37) is in the ON state. Operate the push button switch (12) or (17) to turn on electricity.
When in the N state, the motor operates. The pinion (26) rotates, and the gear shafts (27), (28) and the rack (30) move the operating shaft (8) in the downward direction of the arrow. The changeover switch (2) in (1) is set so that the cam switch part (37) is turned off after moving a sufficient stroke for switching. After the operation shaft (8) has moved, the motor stops in the state of "Fig. 10". In this way, when the operator confirms that the switch of the luminaire has been switched and then turns off the push button switch (12) or (17), the operating axis (8)
Is pulled up again by the restoring force of the tension coil spring (31) and the changeover switch (2) in the lighting device (1). Of course, the pulling force at this time is
It is set to overcome the idling torque when the motor is not energized. 11 and 12 are detailed views of the cam switch unit. In the state shown in FIG. 11, the cam switch portion (37) is in the ON state. When the gear shaft portion (36) rotates from this state by the angle α1 + α2 °, the cam (29)
Rotates β2-β1 °, and the cam switch (37) is OF
After that, the state shown in FIG. 12 is obtained. Here, when the push button switch (12) or (17) is turned off, the actuating shaft (8) is pulled up, the cam (29) is rotated in the reverse direction, and the movable contact piece A is moved.

It can be operated by (9). The above is the description of the switching device that can be attached to and detached from the lighting fixture. next,
A case where an electric switching mechanism is added inside the lighting equipment will be described. "Figure 14" shows the solenoid (39)
Is a method of operating the changeover switch (2).
When the remote control switch (51) is turned on, the solenoid shaft (40) pushes down the switch lever (41) of the changeover switch (2) in the arrow downward direction, whereby (2) is changed over. When the remote control switch (51) is turned off again, the compression coil spring (42)
And the return force of (41) causes the solenoid shaft (4
0) is pulled back to its original position. In addition, the drawstring A (3) can be operated without any trouble with the drawstring near the light fixture.
Can be operated by. Fig. 15 shows the motor (50)
This is a method of rotating the cam lever (43) to operate the switch lever (41). Further, in the normal state, the cam switch portion (49) which is in the ON state is set to be in the OFF state when the switching operation of the switch lever (41) is completed. The solenoid (39) is operated by the operation of this (49). Next, the function and function of the solenoid (39) and the overall structure and mechanism will be described. "FIG. 16" is in a normal state, that is, the remote control switch (51) in "FIG. 15" described above is OF.
In the F state, the solenoid (39) is also in the OFF state and the cam switch portion (49) is in the ON state, but no current has flowed yet. "Fig. 17" shows that the remote control switch (51) is turned on.
When set to N, the cam switch portion (49) is still in the ON state, and therefore the solenoid (39) is also in the ON state.
Therefore, the solenoid shaft (40) pushes down the 3rd pinion (56), and the projection a enters into the groove b provided in the 2nd gear (55), that is, the clutch mechanism is in the connected state. Thus, the rotation of the motor (50) changes from the first pinion (52) to the first gear (53) and the second pinion (5).
4) to the 2nd gear (55), the 3rd pinion (56) to the output gear (57), and the output gear (57) to the cam lever (43). At this time, output gear (5
The torsion coil spring (59) hung on (7) is (5)
It is wound up by the rotation angle of 7). Further, the cam lever (43) rotates and the switching switch (2) of the luminaire switches. At this time, the cam switch section (4
9) is turned off. Here, the operator can confirm that the switch of the lighting equipment has been switched, and when the remote control switch (51) is turned off, the solenoid (39) is turned off and the solenoid shaft (40) is pulled back by the compression coil spring (42). Further, the third pinion is in a state in which the projection a is removed from the groove b by the compression coil spring (58) and the latch mechanism is released. Then,
A torsion coil spring (5
In 9), the force of returning from the rolled-up state to the original state acts and the output gear (57) is reversed, and the cam lever (43) and the third pinion (56) are also reversed. In this way, the state of "FIG. 16" is restored again. When this mechanism is used, when the reduction ratio from the motor (50) to the output gear (57) is set to a large value, it is necessary to reverse the output gear (57) by disengaging the clutch of the train wheel in the middle thereof. The torque can be reduced and therefore the motor (50) can also be operated at a lower torque. Further, the operation by the drawstring A (2) in the vicinity of the light fixture can be performed without any trouble without being influenced by these mechanisms. FIG. 18 is a schematic perspective view of the configuration.
