Description

[Detailed description of the invention] "Industrial application field" This invention is used to switch electric devices that require high safety and confirmation of operation, such as power switches for electric sunshine roofs installed in automobiles. Regarding seesaw switches suitable for

``Prior Art'' Most sunshine roofs installed on automobiles are configured to be opened and closed electrically, and such sunshine roofs can be opened and closed automatically by operating a switch knob while driving. It is convenient because it can be done.

In addition, many sunshine roof electric control switches use a seesaw switch, in which pressing the switch knob seesaws in one direction to open the roof, and seesaws in the other direction to close the roof. It is configured as a switch.

``Problems to be Solved by the Invention'' As mentioned above, the sunshine roof of a car is convenient because it can be opened and closed by operating a switch, but on the other hand, there is a risk of erroneous operation of the switch.

There are times when the sunshine roof opens and people stick their faces, hands, etc. out of the car. This kind of act is often carried out by passengers, especially young people, but if the driver operates the switch to close the roof during this act, the roof may close, causing the face, neck, hands, etc. to be trapped. This creates an extremely dangerous situation. This is because the driver is distracted by driving and does not notice the above-mentioned behavior of the passenger, and also because the driver is driving and does not check the direction of the switch to open or close the roof. This is caused by things that cannot be done.

The above-mentioned erroneous operations can be caused by mischief not only by the driver but also by passengers such as children, and are extremely dangerous.

"Means for Solving the Problems" The purpose of this invention is to solve the above-mentioned problems. For example, when closing the sunshine roof, two switches are required to ensure safety. .

Therefore, in the present invention, in a seesaw switch that includes an operation knob that seesaws when pressed and a switch mechanism that operates the switch in conjunction with this seesaw operation, the operation knob can be moved in the direction in which the operation knob is pressed. A push button is provided, and the push button is provided with a spring that forms a diagonal groove and constantly applies a floating force, and further extends into the diagonal groove to form a driving force direction changing mechanism together with the diagonal groove. A lock member having a protrusion and sliding perpendicularly to the movement direction of the push button in conjunction with the movement of the push button is provided, and the lock member has a lock member that slides in one direction according to the floating of the push button. Therefore, a lock part is provided which extends into the see-saw operation area of the operating knob and locks the operating part, and after the push button is pressed and the lock member is slid in the other direction, the lock part is released. We propose a seesaw switch with a lock, characterized in that the switch mechanism is operated by pressing the operating knob.

According to the seesaw switch configured as described above, in addition to the operation of operating the switch mechanism, there is also the preliminary operation of pressing the push button to release the lock, resulting in a two-motion operation, which may prevent accidental operation. There are almost no problems such as erroneous operation due to pressing the operation knob in the wrong direction.

Furthermore, when the push button is released, the locking member of this seesaw switch slides in one direction in conjunction with the floating force of the push button, so that it is automatically locked as the operating knob moves back.

Therefore, if used as an electrically operated switch for the sunshine roof of an automobile, the roof will not close due to erroneous operation, and the above-mentioned dangerous situation can be prevented in advance.

The seesaw switch according to the present invention can be used not only as an electrically operated switch for sunshine roofs, but also as a power switch, control switch, etc. for other moving devices, electric machines, etc.

"Example" Next, an example of the present invention will be described with reference to the drawings.

Fig. 1 is a front view of the seesaw switch according to the present invention, Fig. 2 is a sectional view taken along line A-A in Fig. 1, and Fig.
The figure is a sectional view taken along the line B--B in FIG. 1.

In these figures, 11 is the switch body,
This has an operating knob 12 with operating parts 12a and 12b protruding from the front, which is rotatably mounted on a support shaft 13, and has an electrical movable contact piece 14 and a fixed terminal 15 inside the body. A switch mechanism is configured.

The operating knob 12 has a T-shape as shown in the figure, and a blind hole with a hole at the tip is formed in the leg, and a protruding member 16 is placed inside the blind hole.
is made to protrude by the expansion action of the spring 17.

The movable contact piece 14 is an elongated conductive plate material, and its central recess is supported by a conductive support plate 19 that stands up from the terminal base 18, making it swingable. The projecting member 16 is brought into contact with the protruding member 16 to be interlocked with the see-saw movement of the operating knob 12.

The terminal base 18 is fixed inside the lower part of the switch body 11, and has fixed terminals 15 facing the contacts provided near both ends of the movable contact piece 14, and a fixed terminal 15 that is electrically connected to the movable contact piece 14. A connection terminal 20 is provided.

The operating knob and switch mechanism comprising the members 12 to 20 described above are known as a seesaw switch, which has been widely used in the past.

21 is a push button with an operating part 21a protruding from the front of the switch body 11, similar to the operating knob 12;
This is to release the lock by moving the slide plate 22 as a locking member.

The push button 21 has a rectangular outer surface and a blind hole 21b with the hole opening located on the lower surface, and the lower half of the push button 21 is inserted into a vertical guide rectangular tube 18a formed integrally with the terminal base 18. A floating force is constantly applied by the expanding pressure of a spring 23 provided between the blind hole 21b and the bottom of the guide rectangular tube 18a.

The slide plate 22 is installed in a narrow space between the upper end surface of the guide square tube 18a and the inner surface of the switch body 11, and when the push button 21 floats due to the expanding pressure of the spring 23, this floating The tip part 2 moves in conjunction with the force and acts as a locking part.
2a is the operating knob 1 as shown in FIGS. 1 and 3.
Advance directly below 2. In addition, this slide plate 22
When the push button 21 is pressed, it moves in the opposite direction to the above in conjunction with this pressing movement, and its tip 22
a is moved back from directly below the operation knob 12.

In this way, the slide plate 22 receives a driving force in a direction (horizontal direction in FIG. 3) perpendicular to the moving direction of the push button 21 (vertical direction in FIG. 3). For that purpose, press button 21
and the slide plate 22 are connected by a driving force direction changing mechanism which will be explained below.

That is, as shown in an enlarged perspective view in FIG. 4, the slide plate 22 has two parallel arms 22.
b, 22c, a distal end 22a integrally formed between the shoulder portions of these arms, and opposed protrusions 22d, 2e provided at the center of each arm 22b, 22c, slightly closer to the distal end.
It is formed by

Further, as shown in an enlarged perspective view in FIG. 5, the push button 21 is a rectangular body with a slightly larger diameter in the lower half and a stepped part 21c in the middle, and the lower half has the blind hole 21b. However, diagonal grooves 21d and 21e of the same shape are provided on both side surfaces.

Note that the diagonal grooves 21d and 21e have spherical edges 21f and 21g at their upper ends (21g is not shown).
are formed, and these will be described later.
The slide plate 22 has two arms 22b,
22c protrudes from both sides of the upper half of the push button 21, and the opposing protrusion 22d is provided for the oblique groove 21d of the push button 21, and the opposing protrusion 22 is provided for the oblique groove 21e.
e are fitted into each other and housed in the switch body 11 in such a connected state.

In the seesaw switch configured as described above, in the normal state, that is, when not operated, each member is in the first position.
The positional relationships shown in Figures 3 to 3 are maintained.

That is, the protruding member 16 provided on the operation knob 12
is in contact with the recess of the movable contact piece 14,
The operation knob 12 and the movable contact piece 14 are stationary in a parallel state as shown in FIG. In this case, the movable contact piece 14 is not in contact with the fixed terminal 15, and the switch mechanism is in a neutral state.
Further, the push button 21 is pushed up by the expanding force of the spring 23 and floats until the stepped portion 21c comes into pressure contact with the two arms 22b, 22c of the slide plate 22. In this state, the opposing protrusions 22d and 22e are connected to the diagonal groove 2.
1d and 21e, and maintains the position to which the slide plate 22 has advanced, that is, the position shown in FIGS. 3 and 6.
When the slide plate 22 moves forward, the tip 2
2a is located directly below one side of the operating knob 12, and the seesaw movement of the operating knob 12 in one direction, that is, the seesaw movement in the clockwise direction in FIG. 2 is prevented.
Therefore, in the normal state, the operating portion 12a of the operating knob 12 is in a state where the operating portion 12a of the operating knob 12 can be pressed.
The pressing operation on b is locked and prevented.

On the other hand, when the push button 21 is pressed, the opposing protrusion 2
2d and 22e are pushed by the upper edges of the diagonal grooves 21d and 21e and move to the upper right in FIG. 6, whereby the slide plate 22 moves backward and enters the operating state shown in FIG. 7.

At this time, the opposing protrusions 22d and 22e are connected to the diagonal groove 2.
It fits into the spherical edges 21f and 21g of 1d and 21e. As a result, the opposing protrusions 22d and 22e do not escape from the diagonal grooves 21d and 21e, and
This fitting prevents the push button 21 from being pressed down.

As shown in FIG. 7, as the slide plate 22 moves, the tip portion 22a moves out from directly below the operating knob 12, allowing the operating portion 12b to be pressed. In this way, when the lock by the slide plate 22 is released, in addition to the seesaw movement of the operation knob 12 in the other direction (the upper counterclockwise direction in FIG. 2), the operation knob 12 also seesaws in one direction (the upper clockwise direction in FIG. 2). Since the movable contact piece 14 seesaws in accordance with the pressing operation of the operating part 12a or 12b and comes into contact with one of the fixed terminals, the switch is closed.

When the pressing force on the push button 21 is released,
Since this push button 21 floats due to the expansion force of the spring 23, the opposing protrusions 22d and 22e are connected to the diagonal groove 2.
It is pushed by the lower edges of 1d and 21e and returns from the position shown in FIG. 7 to the position shown in FIG. 6, from which the operation knob 12 is locked as described above.

The above is just one embodiment, and the present invention can be implemented as follows.

(1) In the above embodiment, the operation part 12 of the operation knob 12
Although the configuration is such that the pressing operation of b is locked, it is also possible to have a configuration in which the pressing operations of the operating sections 12a and 12b are both locked in the same manner as described above.

(2) In the above embodiment, the switch is in the neutral state (second
We have described a seesaw switch that has a neutral state (state shown in the figure), but a switch that does not have such a neutral state, that is, when one side of the operating knob is pushed
It can be implemented as a seesaw switch where one side is turned on and the other side is pushed to turn off.

(3) In the above embodiment, the tip 2 of the slide plate 22
2a extends directly below the operating knob, but the tip 22a may extend to an appropriate position within the see-saw movement area of the operating knob 12.

(4) When using the above-mentioned seesaw switch as an electric operating switch for the sunlight roof of an automobile, the operating section 12a of the operating knob 12
The roof can be opened by pressing the operation part 1.
A switch circuit is formed so that the roof can be closed by pressing 2b.

In this way, if you do not press the push button 21 to release the lock and then press the operation knob 12,
Since the roof does not close, there is extremely little risk of the roof closing due to malfunction.

"Effects" As mentioned above, the seesaw switch according to the present invention is equipped with a so-called two-motion mechanism in which the switch is operated by pressing the operation knob after the lock release operation is performed by pressing the push button. The seesaw switch is automatically locked when the push button is released and the operating knob is moved back, so there is very little risk of inadvertent switch operation or malfunction.

Therefore, it is effective as a switch for electric devices, electric machines, etc. that require reliable switch operation.
