Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an operation switch, and more particularly, to a structure for receiving an operation force on an operation member to perform a contact switching operation.

[0002]

As an operation switch, for example, FIG.
There is a push button switch as shown in B. 7A and 7B are side cross-sectional views, where FIG. 7A shows the off state and FIG. 7B shows the on state. An operation member 71 is housed in the case body 2, and the operation member 71 is held in the case body 2 so as to be movable in directions of arrows 90 and 91. The operation member 71 is exposed from the tip of the case body 2 and can be pressed from the outside. In addition,
The operating member 71 is biased in the direction of arrow 91 by the return spring 75.

A micro switch 3 is housed and fixed at the rear end of the case body 2. The micro switch 3 is provided with terminals 11, 12, and 13. The micro switch 3 has a contact switching movable member 4, and the contact switching movable member 4 is constantly urged in the direction of arrow 91 by urging means (not shown) in the micro switch 3.

The contact switching movable member 4 is in contact with the contact portion 72 at the rear end of the operation member 71. When the contact switching movable member 4 and the contact portion 72 come into contact with each other, the operation member 71 receives not only the return spring 75 described above but also the contact switching movable member 4.

When the push button switch is turned on,
The operating member 71 is pressed in the direction of arrow 90 from the state shown in FIG. 7A. As a result, the contact portion 72 of the operating member 71 presses the contact switching movable member 4 of the microswitch 3 and moves the contact switching movable member 4 in the direction of arrow 90 (FIG. 7).
B). In the microswitch 3, the internal contacts (not shown) are switched according to the movement of the contact switching movable member 4, and the electrical connection of the terminals 11, 12, and 13 is switched.

[0006]

The above-mentioned conventional operation switch has the following problems. First, as described above, the contact portion 72 of the operation member 71 and the contact switching movable member 4 are
Always in direct contact. For this reason, the amount of movement (operation stroke) of pressing the operation member 71 when the switch is turned on is equal to the stroke peculiar to the microswitch 3, that is, the movable range of the contact switching movable member 4. Therefore, when trying to change the operation stroke, there is a problem in that the micro switch 3 itself must be replaced, and an arbitrary operation slot talk cannot be easily selected.

The pressing force (operating load) applied to the operating member 71 when the switch is turned on is determined by the urging force of the return spring 75 and the contact switching movable member 4. Therefore, if the operating load is changed, the return spring 75,
Since the micro switch 3 must be replaced, there is a problem that an arbitrary operating load cannot be easily obtained.

In particular, when the switch is turned on, it is necessary to apply a pressing force that exceeds the switch switching load peculiar to the contact switching movable member 4. Therefore, the operating load cannot be made smaller than the switch switching load in the conventional configuration. .

Therefore, an object of the present invention is to provide an operation switch capable of arbitrarily adjusting the movement amount of the operation member and the operation load.

[0010]

An operation switch according to claim 1 is a case body, an operation member housed in the case body, which moves within the case body by receiving an operation force from the outside, the case body. A switching unit that is housed in the housing, is located in the case body, and performs a contact switching operation according to the movement of the contact switching movable member, and transmits the movement of the operation member to the contact switching movable member. An operation switch comprising a transmission member, which is rotatably held about a transmission fulcrum, wherein the transmission member is rotated by receiving movement of the operation member at a transmission force point. The movement caused by the rotation is transmitted to the contact switching movable member through the transmission action point.

The operation switch according to claim 2 is the operation switch according to claim 1.
The operation switch according to (1) is provided with a spring member for urging the operation member in a direction opposite to the operation force from the outside, and the spring member urges the operation member independently from the movement of the contact switching movable member. The feature is that

[0012]

In the operation switch according to the first aspect of the present invention, the transmission member is rotatably held about the transmission fulcrum. Then, the transmission member rotates by receiving the movement of the operation member at the transmission force point, and transmits the movement due to this rotation to the contact switching movable member through the transmission action point.

Therefore, by selecting the positions of the transmission force point and the transmission action point, it is possible to arbitrarily adjust the movement amount of the operation member and the operation load required to cause the switching unit to perform the contact switching operation.

That is, when the distance from the transmission fulcrum to the transmission force point is set shorter than the distance from the transmission fulcrum to the transmission action point, the movement amount of the operation member becomes relatively small and the operation load becomes relatively heavy. .

On the contrary, when the distance from the transmission fulcrum to the transmission force point is set longer than the distance from the transmission fulcrum to the transmission action point, the movement amount of the operation member becomes relatively large and the operation load becomes relatively large. It gets lighter. In this case, in particular, it is possible to obtain a lighter operating load than the switch switching load specific to the switching unit.

In the operation switch according to claim 2,
A spring member for urging the operating member in a direction opposite to the operating force from the outside is provided, and the spring member urges the operating member independently of the movement of the contact switching movable member.

Therefore, the operating member can be reliably returned by this spring member. For example, in the alternate operation switch, once the contact switching movable member is pressed, the lock mechanism operates and is held, and does not return to the original state until the lock mechanism is released by the next press. Since the operation switch according to the present invention biases the operation member independently of the movement of the contact switching movable member of the switching portion, the contact switching movable member does not return when applied to the alternate type operation switch. Even in the state, the operation member can be surely returned.

1. First Embodiment A first embodiment of the operation switch according to the present invention will be described based on FIG. FIG. 1A is a side sectional view showing an off state, and B is a side sectional view showing an on state. Further, FIG. 1C is a conceptual diagram showing the operation principle. The overall configuration of the operation switch and the operation of the operation switch in this embodiment will be described below in detail.

(1) Overall Configuration of Operation Switch As shown in FIGS. 1A and 1B, the operation member 5 is housed in the case body 2, and the operation member 5 is in the case body 2 in the directions of arrows 90 and 91. Is movably held. The operation member 5 is exposed from the tip of the case body 2 and can be pressed from the outside. Further, a protrusion 5T is formed inside the operation member 5.

At the rear end of the case body 2, a micro switch 3 as a switching unit is housed and fixed. The micro switch 3 is provided with terminals 11, 12, and 13. The microswitch 3 has a contact switching movable member 4, and the contact switching movable member 4 is constantly urged in the direction of arrow 91 by urging means (not shown) in the microswitch 3. . Then, when the contact switching movable member 4 is pressed in the direction of arrow 90, the microswitch 3 switches the internal contacts (not shown) by the movement of the contact switching movable member 4 and the terminals 11, 12 are then switched. , 13
The electrical connection of is switched and the switch is turned on.

A transmission member 6 is interposed between the operation member 5 and the micro switch 3. The transmission member 6 is rotatably supported by a rotation shaft 6J provided on the side wall of the case body 2, and the transmission member 6 has arrows 92, 9 centered around the rotation shaft 6J.
It can be rotated in three directions. The rotating shaft 6J is the transmission fulcrum in this embodiment. The transmission member 6 includes the above-mentioned operation member 5
Of the transmission member 6 and the protrusion 5T are formed as a transmission force point P1.

A pressing member 7 is in contact with the transmission member 6 near the tip (free end) thereof. The contact portion between the transmission member 6 and the pressing member 7 is the action point P2. The tip 8 of the pressing member 7 is in contact with the contact switching movable member 4 of the microswitch 3. The pressing member 7 is the contact switching movable member 4
Is urged in the direction of arrow 91, and the transmission member 6 is urged in the direction of arrow 93 via the pressing member 7. Further, the transmission member 6 causes the operation member 5 to move to the arrow 91.
Biased in the direction.

(2) Operation of Operation Switch Next, the operation of the operation switch in this embodiment will be described. 1A is in the off state, and the operation member 5 is biased by the contact switching movable member 4 as described above, and is biased in the direction of the arrow 91 to project from the case body 2. From this state, the operating member 5 is pressed in the direction of arrow 90. Due to this pressing operation force, the projecting portion 5T of the operation member 5 pushes in the transmission member 6, and the transmission member 6 rotates in the direction of arrow 92 about the rotation center 6J.

By rotating the transmission member 6 in the direction of arrow 92, the pressing member 7 is further moved in the direction of arrow 90, and the tip 8 presses the contact switching movable member 4 of the microswitch 3 (FIG. 1B). . Movable member 4 for switching contacts
When is pressed, the microswitch 3 performs a contact switching operation.

FIG. 1C shows the operating principle when the switch is turned on. The transmission member 6 receives the pressing force of the protrusion 5T of the operation member 5 at the transmission force point P1 and rotates in the direction of the arrow 92. The movement amount L1 of the transmission force point P1 at this time is
It is the same as the operation stroke L1 (FIG. 1B) of the operation member 5. Then, the transmission member 6 transmits this movement to the pressing member 7 through the transmission action point P2, and moves the pressing member 7 in the arrow 90 direction.

Here, the distance from the transmission fulcrum (rotating shaft 6J) to the transmission force point P1 is shorter than the distance from the transmission fulcrum (rotating shaft 6J) to the transmission action point P2. Therefore, the movement amount L2 of the transmission action point P2 becomes larger than the movement amount L1 of the transmission force point P1.

That is, the operation stroke L1 can be made smaller than the stroke (movement amount L2) specific to the microswitch 3. The switch having a small operation stroke L1 may be applied to, for example, an operation switch of a game device.

Further, a transmission force point P1 on the transmission member 6
The operation stroke L1 changes according to the position of. Therefore, by exchanging the operation member 5 and selecting the position of the protrusion 5T (FIGS. 1A and 1B), an arbitrary operation stroke L1 can be obtained.
Can be obtained.

Further, since the distance from the transmission fulcrum (rotation shaft 6J) to the transmission force point P1 is shorter than the distance from the transmission fulcrum (rotation shaft 6J) to the transmission action point P2, a switch unique to the microswitch 3 is provided. It is possible to obtain the operating member 5 having a heavier operating load than the switching load.

The operating load of the operating member 5 also changes according to the position of the transmitting force point P1 on the transmitting member 6. Therefore, the operation load can be arbitrarily adjusted by replacing the operation member 5 and selecting the position of the protrusion 5T (FIGS. 1A and 1B). When the pressing of the operation member 5 is released, the operation member 5 immediately receives the bias of the contact switching movable member 4 of the microswitch 3 and returns in the direction of arrow 91.

2. Second Embodiment A second embodiment of the operation switch according to the present invention will be described based on FIG. FIG. 2A is a side sectional view showing an off state, and B is a side sectional view showing an on state. Further, FIG. 2C is a conceptual diagram showing the operating principle. The transmission member 10 is
It is held by the case body 2 so as to be rotatable about the rotation shaft 10J in the directions of arrows 92 and 93. The projection 15T of the operation member 15 is in contact with the transmission member 10.
The pressing member 7 is also in contact with the transmission member 10.

In this embodiment, the transmission fulcrum (rotating shaft 10
The distance from J) to the transmission force point P1 is longer than the distance from the transmission fulcrum (rotating shaft 10J) to the transmission action point P2. Therefore, as shown in FIG. 2C, the movement amount L2 of the transmission action point P2 is smaller than the movement amount L3 of the transmission force point P1.

That is, the operation stroke L3 is longer than the stroke (movement amount L2) specific to the microswitch 3. Further, the operation stroke L3 changes according to the position of the transmission force point P1 on the transmission member 10. Therefore, the operating member 15 is replaced and the protrusion 15T (FIGS. 2A and 2B).
An arbitrary operation stroke L3 can be obtained by selecting the position of.

Further, the distance from the transmission fulcrum (rotating shaft 10J) to the transmission force point P1 is longer than the distance from the transmission fulcrum (rotating shaft 10J) to the transmission action point P2. Than switching load
The operation member 15 with a light operation load can be obtained, and the operability can be improved.

The operating load of the operating member 15 is also transmitted to the transmitting member 10.
It changes according to the position of the transmission force point P1 above. Therefore, the operation member 15 is replaced and the protrusion 15T (FIG. 2A,
By selecting the position of B), an arbitrary operation load can be obtained. Other configurations are the same as those in the first embodiment.

3. Third Embodiment An alternation type operation switch having an alternation mechanism in a third embodiment of the operation switch according to the present invention will be described with reference to FIG. 3A is a side sectional view showing an off state, and B is a side sectional view showing an on state. Also,
FIG. 3C is a conceptual diagram showing the operating principle. In this embodiment, a switch 20 having an alternate mechanism as a switching unit is provided in the case body 2.

The switch 20 has a contact switching movable member 24. Then, when the contact switching movable member 24 is pressed in the direction of arrow 90, the switch 20 has the switch 2
Switching of contacts (not shown) installed inside 0 is performed,
The electrical connection of the terminals 21, 22 and 23 is switched to be in the ON state.

The contact switching movable member 24 is constantly operated by an urging means (not shown) in the switch 20 so that the arrow 9 always moves.
It is biased in one direction. Further, in the switch 20, when the contact switching movable member 24 is pressed in the direction of the arrow 90 through the pressing member 25, the engagement bar 26 and the pressing member 25 that constitute the alternate mechanism even after the pressing force is released. The pressed state is maintained depending on the combination. Then, by receiving the next pressing force, the engagement between the engagement bar 26 and the pressing member 25 is released, and the pressing member 25 and the contact switching movable member 24 return in the direction of arrow 91.

Further, in this embodiment, a return spring 27, which is a spring member, is provided between the transmission member 6 and the operating member 5. The return spring 27 biases the operating member 5 in the direction of arrow 91 independently of the contact switching movable member 24 of the switch 20. Further, the return spring 27 biases the transmission member 6 in the direction of arrow 92 to bring the transmission member 6 into contact with the pressing member 25.

When the operating member 5 is pushed in the direction of arrow 90 from the off state shown in FIG. 3A, the transmission member 6 rotates in the direction of arrow 92 in response to this pushing, and the contact switching movable member is pushed through the pushing member 25. 24 is moved in the direction of arrow 90. This state is shown in FIG. 3B.

Also in the present embodiment, as in the first embodiment, the operation stroke L1 is more than the stroke peculiar to the switch 20 (FIG. 1C, movement amount L2) due to the positional relationship between the transmission force point P1 and the transmission action point P2. Can be made smaller. In addition, it is possible to obtain an operation load of the operation member 5 that is heavier than a switch change load unique to the switch 20.

When the pressing of the operating member 5 in the direction of the arrow 90 is released, the switch 20 maintains the pressing state of the pressing member 25 (the state shown in FIG. 3B) by the engagement bar 26 as described above. In the present embodiment, the return spring 27 is provided, and biases the operating member 5 in the arrow 91 direction independently of the contact switching movable member 24. Therefore, even if the pressing member 25 and the contact switching movable member 24 do not return in the arrow 91 direction, the operation member 5 is reliably returned in the arrow 91 direction by the bias of the return spring 27.

When the switch is turned off, the operating member 5 is pressed again in the direction of arrow 90. In response to this pressing force, the engagement between the engagement bar 26 and the pressing member 25 is released, and the pressing member 25 and the contact switching movable member 24 return in the direction of arrow 91, and become the off state shown in FIG. 3A. Other configurations are similar to those of the first embodiment.

The switch 20 is based on FIG. 4 and FIG.
The engagement relationship between the pressing member 25 and the engagement bar 26 that constitute the lock mechanism of the alternate mechanism during the operation of will be described. 4 and 5 are views of the pressing member 25 and the engagement bar 26 as seen from the direction of the arrow 98 (FIG. 3). The shaded portion in the drawing is the convex portion of the pressing member 25, and the engaging groove 25a is formed in the pressing member 25 by this convex portion.

The tip 26a of the engaging bar 26 is bent in an L shape, and the bent tip 26a is located in the engaging groove 25a of the pressing member 25. FIG. 4A shows the off state of the switch, that is, the state of FIG. 3A. In this case, the pressing member 25 is positioned in a state of being moved in the direction of arrow 91 by being biased by the contact switching movable member 24.

When the operating member 5 is pressed, the pressing member 25 also moves in the direction of arrow 90 via the transmission member 6. At this time, the tip end 26a of the engagement bar 26 has a groove 25 for engagement.
It moves along a and is once located at the moving place H1. FIG. 4B shows a state in which the tip 26a of the engagement bar 26 is located at the moving place H1. In this case, the contact switching movable member 24 is pressed in the direction of arrow 90, and the switch 20 is turned on (FIG. 3B).

When the pressing of the operating member 5 is released from the state shown in FIG. 4B, the tip end 26a of the engagement bar 26 moves to the moving place H2 and is positioned in the state shown in FIG. 5A. In this way, by the locking of the alternation mechanism, the pressing state of the pressing member 25 in the direction of arrow 90 is maintained and the pressing member 25 does not return in the direction of arrow 91. In this case, as described above, the operation member 5 is returned in the direction of the arrow 91 by the urging of the return spring 27.

From the state shown in FIG. 5A, the operation member 5 is again
When pressed in the direction of arrow 90, the engaging bar 2 is correspondingly pressed.
The tip 26a of 6 once moves to the moving place H3. This state is shown in FIG. 5B. When the pressing of the operating member 5 is released, the tip 26a of the engaging bar 26 is moved to the engaging groove 2
5a, and returns to the state shown in FIG. 4A. In this way, the pressing member 25 and the contact switching movable member 24 are released by releasing the locked state of the alternate mechanism.
Moves back in the direction of arrow 91.

FIG. 6A is a side sectional view showing an off state, and B is a side sectional view showing an on state. In the present embodiment, the transmission member 40 is held in the case body 2 by being in contact with the fixing member 41, rather than being pivotally supported by the rotating shaft provided in the case body 2. The fixing member 41 is fixed to the micro switch 3.

When the operating member 5 is pressed in the direction of arrow 90 from the off state shown in FIG. 6A, the transfer member 40 receives this pressing and the contact point (transmission fulcrum P3) of the fixing member 41 is centered in the direction of arrow 92. Turn to. And the transmission member 4
When 0, the contact switching movable member 24 is moved in the direction of arrow 90 through the pressing member 25, and the switch is turned on. This state is FIG. 6B.

Also in this embodiment, as in the first embodiment, the operation stroke L1 is smaller than the stroke (movement amount L2) peculiar to the microswitch 3 due to the positional relationship between the transmission force point P1 and the transmission action point P2. Can be done (see FIG. 1C). Further, it is possible to obtain the operation member 5 having a heavier operation load than the switch switching load specific to the micro switch 3.

As described above, the transmission member 40 is the case body 2
Since it is held in the case main body 2 by coming into contact with the fixing member 41 instead of being pivotally supported by the rotation shaft provided in the operation switch, the work of assembling the operation switch can be simplified. In addition, regarding other configurations,
