Description

[Detailed Description of the Invention] This invention relates to an operating device that can reliably return an operating mechanism by strengthening the spring force of an elastic member in one direction.

2. Description of the Related Art Conventionally, there is a switch operating device as shown in FIG. 1 that operates an operating mechanism using the biasing force of an elastic member. In the figure, reference numeral 1 indicates an operating section slidably provided on the exterior body 2 of the device (not shown);
4 is a spring lever that is provided close to the operating part 1 and is made up of a cam part 3a and a strip-shaped leaf spring 3b that rotates by the sliding force of the operating part; 4 is a coil spring that returns the spring lever 3 to the home position A; Reference numeral 5 designates a switch having a slider 5a connected to the tip of the leaf spring 3b and slidable in the left-right direction in the drawing by the biasing force of the slider 5a.

When the operating part 1 of this device is slid upward in the figure, the operating part 1 comes into contact with the cam part 3a of the spring lever 3, so the spring lever 3 is pushed counterclockwise against the biasing force of the coil spring 4. It can be done. This rotation of the spring lever 3 brings the leaf spring 3b into contact with the slider 5a. The slider 5a is pushed into the switch 5 by the biasing force of the leaf spring 3b, and the switch 5 is turned on.

On the other hand, when the operating portion 1 is slid downward to turn off the switch 5, the biasing force of the coil spring 4 causes the spring lever 3 to rotate clockwise and return to its home position. This return of the spring lever 3 generates a biasing force on the leaf spring 3b, and this biasing force pulls out the slider 5a from inside the switch 5, causing the switch 5 to open.
is turned off.

However, with such a configuration, if the sliding resistance of the slider 5a is greater than the return force of the leaf spring 3b, the cam portion 3a of the spring lever 3 will return to the home position due to the biasing force of the coil spring 4. Also, since the biasing force of the leaf spring 3b is smaller than the sliding resistance of the slider 5a, the leaf spring 3b is deflected. This leaf spring 3b
Due to the deflection, the slider 5a stops before the home position A by the deflection distance X, so the slider 5a cannot be completely pulled back, and the return of the switch 5 may be impaired.

This idea was made in order to solve the above problem.A strip-shaped reinforcing member is superimposed on the plate surface of the strip-shaped elastic member that operates the operating mechanism, and one end is fixed to restore the operating mechanism. It is an object of the present invention to provide an operating device that can significantly improve the returnability of the operating mechanism section by strengthening the spring force of the elastic member in this direction.

An embodiment of this invention will be described below with reference to the drawings. This embodiment shows an example in which this invention is applied to a switch device. In FIGS. 2a and 2b, reference numeral 11 denotes an operating section slidably provided on an exterior body 12 of a device (not shown), and a spring lever 13 is rotatably provided near this operating section 11. This spring lever 13 has a strip-shaped elastic member 13b attached to a cam portion 13a.
It is integrally formed. And cam part 13
A part of a is made to protrude from the exterior body 12, and a strip-shaped reinforcing member 14 made of an elastic material having a larger spring force than the elastic member 13b is superimposed on one plate surface (left side in the figure) of the elastic member 13b. , one end of the reinforcing member 14 on the cam portion 13a side is fixed using means such as welding. At this time, the elastic member 13b is made to protrude from the tip of the reinforcing member 14. An operating mechanism, such as a switch 15 provided with a slider 15a, is disposed at the tip of the elastic member 13b and connected to the slider 15a. Here, 16 is a coil spring that returns the spring lever 13 to its normal position.

Now, when the operation part 11 of this device is slid upward in the figure, the cam part 13 protruding from the exterior body 12
The operating section 11 comes into contact with a. In this state, operation unit 1
1 is further slid upward, the cam portion 13a is pushed into the exterior body 12 as shown in FIG. As a result, the spring lever 13 is connected to the coil spring 1.
Because it rotates counterclockwise against the biasing force of 6,
The tip of the elastic member 13b contacts the slider 15a. Therefore, the slider 15a is pushed into the switch 15 by the biasing force corresponding to the deflection dimension δ of the elastic member 13b, and the switch 15 is turned on.

On the other hand, when the operating portion 11 is slid downward in the figure in order to turn off the switch 15, the biasing force of the coil spring 16 causes the spring lever 13 to rotate clockwise and return to its home position. This spring lever 1
6 returns, the elastic member 13b gradually comes into close contact with the reinforcing member 14, so that the spring force of the elastic member 13b increases. The rotational force of the elastic member 13b and the reinforcing member 14 pulls the slider 15a out of the switch 15, turning the switch 15 off.

Therefore, according to such a configuration, by overlapping the reinforcing member 14 on one plate surface of the elastic member 13b and fixing one end thereof, the elastic member 13b can be easily fixed.
Since the spring force in one direction b can be strengthened, the slider 15a of the switch 15 can be reliably returned to its original position with a simple configuration, and the reliability of the product can be improved.

Note that this invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without changing the gist.

For example, in the embodiment described above, the reinforcing member that strengthens the spring constant of the elastic member is made of an elastic material, but the invention is not limited to this, and the reinforcing member may be made of a rigid material instead.

Further, in the above embodiment, this invention is applied to a switch, but this invention is not limited to this as long as the operating mechanism can be operated by the biasing force of a strip-shaped elastic member in both folding directions.

As described above, according to this invention, a strip-shaped reinforcing member is superimposed on the plate surface of the strip-shaped elastic member that operates the operating mechanism section, and one end is fixed, and the elastic member is moved in the return direction of the operating mechanism section. By strengthening the spring force, it is possible to provide an operating device that can reliably return the operating mechanism section.
