Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
A switch device of a so-called four-direction push operation type that performs a push operation at four locations in a direction, and a four-way switch equipped with an interlock mechanism that restricts push operations of push plates at two or more locations at the same time. The present invention relates to a device, and more particularly to a compact 4-way switch device.

[0002]

2. Description of the Related Art Generally, in a four-way switch device, push plates which are pushed at four positions in four directions (cross directions) are swingably attached to a case. The switch is arranged. This four-way switch device is used, for example, in combination with a two-way switch device as a switch device for tilting the left and right mirror surfaces of an electric remote control mirror for an automobile in the vertical and horizontal directions. That is, a first driving motor for tilting the left mirror surface in the vertical direction, a second driving motor for tilting the left mirror surface in the horizontal direction, and a second driving motor for tilting the right mirror surface in the vertical direction. Among the third drive motor and the fourth drive motor for tilting the right mirror surface in the left-right direction, it is used as a control switch device for rotating a desired motor in the forward or reverse direction.

[0003]

However, in the above-mentioned conventional four-way switch device, when the push plates are simultaneously pushed at two or more locations due to an erroneous operation, the power is short-circuited or the motor is supplied with power. There is a problem that you can not do it.

Therefore, a four-way switch device equipped with an interlock mechanism for restricting the push operation of the push plate at two or more locations at the same time (actually 1-41).
No. 141) was filed first. In this four-way switch device, a regulating member can slide in a case in a plane substantially parallel to the push plate in four directions (a cross direction connecting two opposite positions out of four positions for pushing the push plate). The restriction portion is provided around the restriction member so as to face the push plate. In this four-way switch, when the push plate is pushed at one place, the regulating member slides in the direction opposite to the one place where the push plate is pushed, so that the push plate is regulated on the slide side. The portion regulates the push operation at a portion on the side opposite to the push operation side of the push plate.

However, in this four-way switch device, the regulating member is slidable in four directions on a plane substantially parallel to the push plate in the case, so there is a problem that the entire device becomes large.

It is an object of the present invention to provide a four-way switch device which is more compact.

[0007]

According to the present invention, in order to solve the above problems, four actuators are arranged in four cases in two diagonal directions with respect to four operation directions of a push plate in a case. In addition, four sets of switches are arranged in the case corresponding to the four actuators, respectively, and the rotating body is rotatable in the case around an axis substantially perpendicular to the push plate. The push plate is provided with two convex portions on one diagonal side of the actuator side, and two sets of inclined surfaces are provided on the rotary body as the two convex portions. Correspondingly, and provided in the rotation direction of the rotating body, the two sets of inclined surfaces and the two convex portions are provided with two sets of switches by a push operation at one position of the push plate. When the switch is turned on, one convex portion on the push operation side of the push plate is pushed and slides on one set of inclined surfaces to rotate the rotating body, and the other one set of inclined surfaces becomes By contacting one convex part of
It is characterized in that there is a relative positional relationship that restricts push operations at the other three positions of the push plate and restricts turning on of the other two sets of switches in the OFF state.

[0008]

According to the present invention, when the push plate is pushed at one place to turn on two sets of switches through the two actuators to form a desired circuit, the push operation side is constituted by the above construction. One of the convex portions slides on the one set of inclined surfaces to rotate the rotating body, and the other one set of inclined surfaces abuts the other one convex portion. As a result, the push operation at the other three positions of the push plate can be restricted, and the turning on of each of the other two sets of switches in the OFF state can be restricted. The interlock mechanism of the present invention restricts the ON operation of each of the other two sets of OFF switches by the descending operation of the convex portion and the rotating operation of the rotating body. It can be made compact as compared with a conventional four-way switch device that slides in four directions.

The four-way switch device of the present invention in this embodiment has the above-mentioned structure, and its operation will be described below. First, the states shown in FIGS. 4, 5, 7, and 9 are normal states (neutral states). In this state, when the upper portion of the switching knob 80 is tilted in the arrow direction (left direction) in FIG. 5, for example, the pin 84 at the lower portion of the switching knob 80 is inclined surface 8 in the arrow direction (right direction) in FIG.
3 to move over and move along with the slider 81.
The contact 82 slides in the direction of the arrow (rightward) in FIG. 5, and the movable contacts of the two contacts 82 electrically contact the fixed contacts on the lower surface of the electric circuit board 6 to form a desired electric circuit. It When the upper portion of the switching knob 80 is tilted in the direction opposite to the arrow in FIG.
4 moves over the inclined surface 83 in the direction opposite to the arrow in FIG. 5 (leftward) and returns to the original position, and the slider 81 and the contact 82 slide in the direction opposite to the arrow in FIG. 5 (leftward). To return to the original normal state. Further, when the switching knob 80 in the normal state is tilted in the direction opposite to the arrow in FIG. 5 (rightward), the slider 81 and the contact 82 slide in the direction opposite to the arrow in FIG. An electric circuit is constructed.

Then, the push plate 3 is pushed at a certain location, for example, the "upper" location. Then
Two adjacent actuators (first actuator 41 and second actuator 42) corresponding to the push-operated portion of the push plate 3 are pushed and moved downward, and the two actuators (first actuator 41 and second actuator 42). 42) operating parts 400, 4
00 is the movable contact 510 and 520 of the rubber contact 5.
, 530 and 540 are pushed down against the elastic force of the flexible portion 501, and the movable contacts 510 and 520 and 530 and 540 of the rubber contact 5 are fixed contacts 511, 512 and 521, 522 and 531 of the electric circuit board 6, 5
32 and 541, 542 are electrically contacted, and the first set of switches 51, 52 and the second set of switches 53, 54 are O
N (see FIG. 10A).

At this time, the first actuator 41 located at the upper left of the two lowered actuators described above.
6 slides on the right inclined surface of the first set of inclined surfaces 71 (see FIGS. 9B and 10B), and the rotating body 7 rotates clockwise in FIG. 6 (see FIG. 8). Then, the convex portion 410 of the first actuator 41 is located at the valley of the first inclined surface 71 by rotating in the direction of the arrow in FIG. This rotating body 7
The left inclined surface of the second inclined surface 72 of the rotating body 7 comes into contact with the first actuator 41 and the convex portion 410 of the third actuator 43 located on the lower right corner of the diagonal line (FIG. 10B. See)). For this reason, during the push operation at the "upper" portion of the push plate 3, the push operation at the "right" and "lower" portions of the push plate 3 becomes impossible. Also, push plate 3
Is a single plate (integrated plate), and the convex portion 410 of the first actuator 41 is in contact with the first inclined surface 71 of the rotating body 7, so that the “upper” portion of the push plate 3 is During the push operation of, the push operation at the "left" portion of the push plate 3 means that either the "up" portion or the "left" portion is pushed with the contact point as the fulcrum. , "Up" and "left" cannot be pushed at the same time.

As a result, the push plate 3 is restricted from being pushed at the other three positions "right", "down", and "left", and the other two sets of switches in the OFF state (third set).
Switches 55, 56 of the set and switches 57, 5 of the fourth set
It can be regulated that 8) turns on.

When the "right" portion of the push plate 3 is pushed, the convex portion 410 of the third actuator 43 located at the lower right slides on the second inclined surface 72, is located at the valley thereof, and is rotated. The body 7 rotates in the direction (counterclockwise) opposite to the arrow in FIGS. 8 and 10 (B), and the first inclined surface 71 of the rotor 7 is located on the diagonally upper left with the above-mentioned third actuator 43. The convex portion 4 of the first actuator 41
The push operation of the push plate 3 at the other three positions “up”, “down”, and “left” is restricted. Further, even in the push operation at the “lower” position or the “left” position of the push plate 3, the push operation at the other three positions of the push plate 3 is restricted as described above. Moreover, even when the entire push plate 3 is pushed, the four lock switches 51 to 58 are prevented from being turned on by the interlock mechanism. When the push operation of the push plate 3 is stopped, the flexible portion 501, which is elastically deformed by being pushed down by the operating portion 400 of the actuator on the push operating side, returns to its original state due to the elastic return force. The actuator on the operating side rises and the push plate 3 returns to the original state (normal state or neutral state).

As described above, in the interlock mechanism of the present invention in this embodiment, two sets of other switches in the OFF state are operated by the lowering operation of the convex portion 410 of the actuators 41 to 44 and the rotating operation of the rotating body 7. Since it regulates that each of the switches turns ON, it can be made compact as compared with the conventional four-way switch device in which the regulating member slides in four directions.

Further, since the four-way switch device of the present invention in this embodiment uses the rotating body 7 of the ring member, the circular through hole 76 in the center of the rotating body 7 can be utilized. For example, as in this embodiment, since the two-way switch device 8 can be arranged at the center of the four-way switch device of the present invention through the central circular through hole 76 of the rotating body 7, it can be made more compact. You can

In the above-described embodiment, the first inclined surface 71 and the second inclined surface 72 of the rotating body 7 are substantially V-shaped, but the first actuator 41 and the third actuator 4
The one side slope may be used as long as it contributes to the abutment slide of the third protrusion 410. For example, in FIGS. 9 and 10, the first inclined surface 71 is the right inclined surface and the second inclined surface 72 is the left inclined surface. Further, in the above-described embodiment, the first recess 73 and the second recess 74 of the rotating body 7 are provided.
Is not always necessary. In this case, the second actuator 4
The convex portions 410 of the second and fourth actuators 44 are unnecessary.

In particular, in the four-way switch device of the present invention in this embodiment, the four actuators 41 to 44 are located at four positions on two diagonal directions with respect to the four operating directions of the push plate 3, that is, on the push plate 3. Since it is arranged at each of the four corners, push plate 3
When the push operation is performed in one of the operation directions, for example, the “up” direction, as shown in FIGS. 11A and 11B, the elastic engagement claw 30 on the side opposite to the push operation side of the push plate 3 is provided. The distance L2 from the fulcrum S, which is the engagement point between the engagement hole 17 of the case 1 and the two actuators (third actuator 43 and fourth actuator 44) on the opposite side of the push operation side, from the fulcrum S to the push operation. Since it is extremely smaller than the distance L1 to the two actuators on the side (first actuator 41 and the second actuator 42), the two actuators on the side opposite to the push operation side (the third actuator 43 and the fourth actuator 44). ) Of the two actuators (first actuator 41 and second actuator 42) on the push operation side. It is extremely smaller than the penetration depth of T1. As a result, two sets of switches (third set of switches 55 and 56 and fourth set of switches 57 and 58) are provided via the two actuators (third actuator 43 and fourth actuator 44) on the side opposite to the push operation side. ) Is false ON
In order to prevent this, in the OFF state (state in which the push plate 3 is not pushed in any direction) shown in FIG. Depression amount T of the third actuator 43 and the fourth actuator 44)
The switch is erroneous if you secure a small gap of 2
It is possible to reliably prevent N.

Further, the push plate 3 is pushed at one place (one direction), and the convex portion 410 of one of the actuators on the diagonal line and the one slanted surface of the rotary body 7 are brought into contact with each other so that the rotary body 7 is rotated. In order to rotate, the gap between the convex portion of the other actuator and the other inclined surface of the rotating body 7 corresponding to the pushing amount T2 of the two actuators on the side opposite to the push operation side is required. is there. That is, if there is no gap corresponding to the pushing amount T2, even if the push plate 3 is pushed at a certain location (one direction), the projections 410 of the two actuators on the diagonal line form two sets of the rotating body 7. This is because the rotating body 7 cannot rotate by coming into contact with the inclined surface of. As a result, the pushing amount (T1−T2) corresponding to the pushing amount T1 of the push operation side actuator minus this gap T2 contributes to the rotation of the rotating body 7. Since the gap T2 is small as described above, the pushing amount (T1-T2) that contributes to the rotation of the rotating body 7 is large, and the rotating amount of the rotating body 7 is large. When the rotation amount of the rotating body 7 becomes large, the contact area between the convex portion 410 of the actuator on the side opposite to the push operation side and the inclined surface of the rotating body 7 becomes large, and the other portion (direction) of the push plate 3 Since the restriction range of the push operation is large, the actuators 41 to 44 and the rotating body 7 do not require high dimensional accuracy, and the push plate 3 is
It is possible to sufficiently restrict simultaneous push operations at more than one place.

The light-transmissive mark 31 is formed by coating an opaque paint on a portion other than the mark 31 on the outer surface of the push plate 3 made of a light-transmissive synthetic resin. Alternatively, the push plate 3 is formed by two-color molding in which a portion corresponding to the mark 31 is made of a light transmissive synthetic resin and the other portion is made of an opaque synthetic resin. That is, the mark 31 is configured to be illuminated by the light projected from the four light source bulbs 300 described later.
