Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch mechanism. In particular, the present invention relates to a switch mechanism suitable for tilting a remote control mirror of an automobile.

It is known to use a four-way switch to tilt an automotive remote control mirror in a desired direction, up, down, left, or right.

However, when applying such remote control mirror adjustment, since the mirrors are usually located on the left and right sides of the car, two multi-directional switches are required to control each side, which is costly. However, there are also problems in terms of installation space and ease of operation. For this reason, a configuration may be considered in which both are controlled by a single multi-directional changeover switch, but in that case, it would be necessary to provide a separate changeover switch to determine which side is to be operated. This may complicate the overall structure and make it difficult to assemble, which may lead to increased costs, and since two switches must be operated, there is a risk of erroneous operation.

In view of the above circumstances, the present invention can achieve multi-directional switching and two-directional switching with one switch mechanism,
Moreover, it is an object of the present invention to provide a switch mechanism in which each operation can be performed using a single operator, and there is no risk of erroneous operation despite the use of a single operator.

An example of the implementation of the present invention will be described below with reference to the drawings.

1 to 9 show an embodiment of the present invention.

As shown in the figure, the switch mechanism of the present invention includes a multi-directional changeover switch section 1 configured to achieve desired switching and a two-way changeover auxiliary switch section 2 disposed within a common frame 3. The direction changeover switch part 1 includes a contact 6 that performs switching by sliding on a contact structure 5 carried by a movable piece 4, and the auxiliary switch part 2 has a contact structure 5 carried by an auxiliary movable piece 7. Auxiliary contact piece 8 sliding on 5'
The movable piece 4 and the auxiliary movable piece 7 are selectively operated by a single operator 9 disposed through the upper part of the frame body 3.

When the switch mechanism configured in this way is used for mirror tilting of a remote control mirror for an automobile, it is determined by switching the auxiliary switch section 2 whether the left or right mirror is to be controlled, and then the multi-directional changeover switch section is used. 1, the mirror can be configured to tilt as desired.

The configuration of the illustrated example will be described in detail below.

In the present invention, the multi-directional changeover switch section 1
The switching is performed by tilting the operator 9 inserted into the frame 3 through the upper opening 3a of the frame 3, as shown in FIGS. 1 and 2. The head of the operator 9 is a plate-shaped operation part 91, and the operator 9 is supported within the frame 3 by the neutral position automatic return mechanism 12, so that the side of the operation part 91 can be pushed. This allows the operator 9 to be tilted. For example, if you press part A in Figure 1, the control will turn to the arrow
Tilt in direction A′. Note that the center portion of the operator 9 serves as a shaft portion 92.

A fixing member 31 is fixed inside the frame 3 with its side surface in close contact with the inner surface of the frame 3. The upper surface of this fixing member 31 supports the lower part of the automatic return mechanism 12, and the lower surface is in contact with the upper surface of the guide member 32. The lower end of the operator 9 is inserted into the movable piece 4, and when the movable piece 4 moves due to the tilting of the operator 9, the contact 6 attached to the bottom surface of the movable piece 4 is carried by the movable element 4 and moves to the base. By sliding over the contact structure 5 on 33 the desired switching is achieved.

The automatic return mechanism 12 includes a hemispherical upper sliding member 10 fixed approximately at the center of the operator 9, and a hemispherical lower sliding member 10' provided below the operator 9 so as to be slidable in the axial direction thereof. , a spring 13 interposed between both members 10, 10', and a spring 1
3, the spherical portions of each sliding member 10, 10' are pressed against the frame 3 and fixed member 31, respectively, and when the operator 9 is released after operation, the operator 9 is automatically moved to the neutral position by the restoring force of the spring 13. Allow it to return to its position. For this purpose, a tapered recess is formed in the upper inner surface of the frame body 3, and a tapered recess is also formed in the upper surface of the fixing member 31.

Further, as shown in FIG. 7, the upper sliding member 10 has two cylindrical shafts 10a projecting laterally at its lower part. This shaft 10a is normally located in a groove 3b (or groove 3c) provided on the inner surface of the frame 3, and functions to allow the operator 9 to tilt. When pressed downward, the actuator 21 is engaged with the actuator 21 that switches in two directions, and the actuator 2 is rotated by rotating the operator 9.
It plays the role of an engaging member that drives the auxiliary movable piece 7 and thereby achieves two-way switching.

The groove provided on the inner surface of the frame 3 includes a groove 3b;
There is a groove 3c formed at right angles to this, and both form a substantially cross shape. These grooves 3b and 3c have a width d approximately equal to that of the shaft 1 protruding from the upper sliding member 10.
0a to the extent that can be accepted, and in this, axis 1
0a can rotate around an axis as indicated by arrow B in the figure. This rotation is performed by A of the operator 91.
Move the operator 9 in the left and right directions in Fig. 1 by pressing the
In FIG. 2, this is done when tilting is performed along a line perpendicular to the plane of the paper (that is, in a direction from the plane of the paper toward the spine of the paper, for example).

On the other hand, the grooves 3b and 3c are provided with a margin in the vertical direction, and for example, by pressing section C in FIG. When tilting in the left and right direction, the operator 9 and the automatic return mechanism 1 attached to it
2 tilts around point Q, and at that time, axis 1
0a allows tilting as indicated by arrow D in the figure.

When the necessary operation is completed and the pressing of the operating part 91 is stopped, the operating element 9 is returned to the neutral position by the automatic return mechanism 12, and the movable element 4 and the contact element 6 are returned to their original positions.

In this embodiment, as described above, the tilting motion of the operator 9 is transmitted to the movable element 4, which moves the contact element 6 on the bottom surface of the movable element 4. As shown in the figure, it has a rectangular plate shape, with rising pieces 32a formed on two opposing sides, and hanging pieces 32b formed on the other two opposing sides, 32a and 32b forming approximately right angles to each other. I am doing it. Note that a hole through which the operator 9 passes is formed in the center.

The rising piece 32a of the guide member 32 is received in a groove 31a provided oppositely on two sides of the lower surface of the fixed member 31, and extends in the left-right direction in FIG. 2 (direction perpendicular to the paper surface in FIG. 1). Sliding is guided. When moving in this manner, the movable piece 4 is slid in the same direction by the hanging piece 32b. In addition, in the case of sliding in a direction perpendicular to this, that is, in the left-right direction in FIG. The movable piece 4 slides along the hanging piece 32b of the guide member 32. Hanging piece 32b of movable piece 4
The plane along the line is indicated by reference numeral 41 in FIG. The contactor 6 attached to the movable piece 4 has a substantially right triangular shape as shown in FIG. The upright piece 62 in the figure is the movable piece 4.
The movable piece 4 is attached to the bottom surface of the movable piece 4 via a coil spring 61 in close contact with the side surface of the movable piece 4 . The movable piece has 2
Three contacts 6, 6' are attached, and each contact has three contact points a, b, c, d, e, f projecting downward.

Next, the switching structure of the auxiliary switch section for two-way switching will be explained.

The auxiliary switch section 2 of the present invention is capable of two-way switching by a contact piece 8 supported by an auxiliary movable piece 7 and moving on a contact structure 5', and the operation is also an operation used for multi-directional switching. The operation of the auxiliary switch section 2 by the operator 9 is performed via the actuator 21.

That is, the upper sliding member 10 is normally pressed against the upper inner surface of the frame 3 by the spring 13, and the actuator 21 is connected to the upper sliding member 10 as shown in FIGS. 1 and 2. It is supported on the upper surface of the fixing member 31 at the lower part. The actuator 21 is formed with a through hole 21' into which the upper sliding member 10 can fit when the operator 9 is pushed down against the spring 13. Continuing from this, a groove 21a is formed in which the shaft 10a protruding from the upper sliding member 10 can be engaged. In addition, this actuator 2
1 has an elongated hole 22 at the end, as shown in FIG. 4, and the protrusion 71 of the auxiliary movable piece 7 is inserted into the elongated hole 22, so that when the actuator rotates, the movable piece 7 can be moved. It is configured so that it can be done.

When attempting to achieve two-way switching, when the operating portion 91 is pressed down and the upper sliding member 10 is moved downward, the shaft 10a engages with the groove 21a of the actuator 21, as shown by the broken line in FIG. do. A top view of the engaged state is shown in FIG. Therefore,
When the operator 9 is rotated in this state, the operator 9 and the upper sliding member 10a engage with each other at the D-cut portion 92a (see Figs. 6 and 7) and become one body in the rotational direction. , the upper sliding member 10a also rotates integrally, and at the same time, the actuator 21 also rotates. Therefore, for example, if the operator 9 is turned in the direction of arrow E in the state shown in FIG. 4, the upper sliding member and its shaft will also rotate, and the actuator 21 will also rotate. This actuator 21 has an elongated hole 22 at the end, and the protruding shaft 71 of the auxiliary movable piece 7 is inserted into the elongated hole 22, so that the auxiliary movable piece 7 is moved downward, that is, in the direction of arrow F, by the above rotation. , thereby achieving switching.

After switching, when the pressure on the operator is stopped, the upper sliding member 10 is pushed upward by the spring 13, and the shaft 10a disengages from the groove 21a of the actuator 21, and at the same time, the shaft 10a is removed from the other side of the frame 3. This enables the operator 9 to be tilted by engaging with the groove 3c.

In the figure, reference numeral 23 indicates a ball, and by providing a recessed portion for receiving the ball at a corresponding position on the upper inner surface of the frame 3, switching can be achieved with a sense of moderation. Also, 23' is a long hole that can be bent.

As a two-way switching mechanism, a mechanism as shown in FIG. 10 can also be used. The actuator 21 is generally ring-shaped, and engages with the auxiliary movable piece 7 using engagement teeth 25 and 72. However, unlike the one in FIG. 4, there is no sense of moderation due to the ball 23 and the recessed portion of the frame body 3, so this sense of moderation is provided by the auxiliary movable piece 7. That is, the auxiliary movable piece 7 is provided with an abutment member 72 that protrudes laterally in the hole 73, and is brought into elastic contact with the frame 3 by the spring 74 in the hole 73. Recesses 3a, 3b, and 3c are provided in the corresponding portions, and the abutment member 72 fits there to provide a sense of moderation. Note that the central recessed portion 3b is not switched to either of the two directions, and the recessed portion 3b is
a, 3c are contact members 72 to facilitate switching.
The recessed part 3 is tapered along the sliding direction of the
b is formed at its tapered top.

In addition, this sense of moderation is achieved by providing a protrusion 75 on the auxiliary movable piece 7 and forming an elongated notch 76 so that it can bend in the direction of the arrow, as shown in No. 11, and recesses 3a to 3c corresponding to the frame body 3. It may also be provided.

As described above, the switch mechanism of the present invention includes a multi-directional changeover switch section configured to achieve desired switching and a two-way changeover auxiliary switch section disposed within a common frame, and the multiway changeover switch section configured to achieve desired switching. is inserted into the frame so that it can be tilted and rotated, and is carried by a movable piece that is moved by the tilting of the operator, which is biased upward by the spring pressure of the automatic neutral position return mechanism, and slides on the contact structure. The two-way switching auxiliary switch portion includes an auxiliary contact that is carried by an auxiliary movable piece and slides on the auxiliary contact structure to perform switching, and the auxiliary movable , the switching is performed by the rotation of the actuator, and the operator and the actuator are configured such that the operator and the actuator are both rotated in the direction of rotation only when the operator is pushed in against the spring pressure of the automatic neutral position return mechanism. Since it is configured to work in conjunction with each other, multi-directional switching can be performed by tilting a single operator, and
Two-way switching can be performed by pushing and rotating the operator, and in particular, the two-way switching cannot be performed unless the operator is pushed once, so it is possible to make erroneous operations for two-way switching and multi-directional switching. fear can be eradicated.
