Description

[Detailed description of the invention] The present invention relates to a switch mechanism.

In particular, the present invention relates to a switch mechanism that incorporates a four-way changeover switch section and a two-way changeover switch section within a single frame. Conventionally, four-way changeover switches have been used for remote control of automobile mirror devices, etc.

However, since the car mirror device is located on the left and right sides of the car, two 4-way changeover switch sections must be provided for each adjustment, or one 4-way changeover switch and two 4-way changeover switches must be used for each adjustment. It is necessary to use both a direction changeover switch and a direction changeover switch. The arrangement of these two switches is
There are problems in terms of space and installation work, and there is also the problem of impairing the ease of operation. In view of the above circumstances, the present invention is capable of achieving four-way switching and two-way switching with a single switch mechanism, and each operation can be performed using a single operating lever, thereby making the structure simple and easy to assemble. It is an object of the present invention to provide a switch mechanism with good performance and operability.

Hereinafter, an example of implementation of the present invention will be described with reference to the drawings.

The illustrated example is an application of the present invention to a remote control of an automobile mirror device. As shown in the figure, the switch mechanism of the present invention includes a four-way changeover switch section 1 and a two-way changeover switch section 2 disposed within a single frame 3.
The direction changeover switch section 1 performs switching by tilting and operating the operation lever 9 inserted into the frame body 3 from the upper part thereof, and the two-way changeover switch section 2 performs switching by tilting and operating the operation lever 9 inserted into the frame body 3 from above. The configuration is such that switching is performed by rotation around the axis.

The four-way changeover switch section 1 and the two-way changeover switch section 2, which are operated by the aforementioned operation lever 9, are constructed as follows.

The four-way changeover switch section 1 includes a contact structure 5 disposed on a base 33 forming the bottom of the frame 3 in order to achieve desired switching, and a contact 6 that slides on the contact structure 5 to effect switching. and a movable piece 4 that supports this contactor 6. The contactor 6 is assembled into two substantially right triangular pieces as shown in FIG. 6 and assembled to the movable piece 4 via a spring 61. It has three rear contact parts a, b, c, d, e, f on its bottom surface that protrude in the direction of the contact structure 5, and when the operating lever 9 is tilted left and right or in the front and back direction, the movable piece 4 and the contact 6 is configured to perform cutting by sliding to the right, left, rear, or forward on the contact structure 5.

For this reason, in the illustrated embodiment, a fixing member 31 having grooves 31a provided oppositely on two sides of the lower surface is fixed to the frame 3, and on the other hand, as shown in FIG. A guide in which two opposing side pieces are provided with rising pieces 32a that are slidably engaged with the grooves 31a, and hanging pieces 320 are provided on the other two opposing side pieces to hold the movable piece 4 from both sides. A member 32 is formed, and the pair of rising pieces 32a of the guide member 32 are iron-fitted to the grooves 31a of the fixed member 31, and the side surface 41 of the movable piece 4 is connected by the pair of hanging pieces 32b.
When the operating lever 9 is held from both sides and the shaft portion 92 at the lower end of the operating lever 9 is inserted into the hole provided in the movable piece 4, and the operating lever 9 is tilted in the direction of arrow A in FIG. Since the piece 32a is competing with the groove 31a, it cannot move, but the movable piece 4 slides along the hanging piece 32b of the stopped guide member 32, and the operating lever 9 is moved to a position perpendicular to the arrow A. When the guide member 32 is tilted in the direction indicated by the arrow C in FIG. The piece 4 is configured to slide so that switching in four directions can be performed by tilting the operating lever 9 in the direction of arrow A or C.

An upper sliding member 10 having a hemispherical upper surface is formed below the operating lever 9, and the upper surface of the upper sliding member is brought into contact with the upper inner surface of the frame 3, and the lower part of the operating lever 9 A lower sliding member 10' having a hemispherical lower surface is vertically slidably aligned with the rut 92, and the lower sliding member 10' is brought into contact with a concave portion on the upper surface of the fixing member 31, and A coil spring 13 is interposed between the vertical sliding members 10 and 10' to constitute an automatic neutral position return mechanism 12 for the operating lever 9.

That is, with this configuration, since the operating lever 9 is tilted by compressing the coil spring 13, when the operating lever 9 is released after being tilted, the lower sliding portion is tilted by the restoring force of the coil spring 13. 10' automatically returns to the position where it has fallen into the lower end of the slotted recess of the fixing member, that is, to the position where the operating lever 9 is vertical. The two-way changeover switch section 2 has an auxiliary contact structure 5' arranged on the same base 33 as the contact structure of the four-way changeover switch section, and slides over this auxiliary contact structure 5' to perform two-way switching. The auxiliary movable piece 7 is equipped with an auxiliary contact 8 and an auxiliary movable piece 7 supporting the auxiliary bush contact 8, and the auxiliary movable piece 7 is guided by a fixed member 31 so that it can slide in the switching direction, and the knob of the operating lever 9 When 91 is rotated around its axis, the auxiliary movable piece 7 slides and can switch between two directions.

That is, the upper sliding member 1 is shown in FIGS. 3 and 7.
As shown in the figure, a groove 21a of a ring-shaped actuator 21 is formed with a pair of shafts 10a projecting in the diametrical direction, and the pair of shafts 10a are arranged so as to surround the upper sliding member 10.
When the knob 91 of the operating lever is rotated around the axis, the ring-shaped actuator 21 is rotated to the operating lever 9.
Rotate around the axis.

A gear 25 is formed on a part of the outer periphery of the ring-shaped actuator 21, and a rack tooth 72 is formed on the upper end of the auxiliary movable piece 7.
When the knobs 91 are engaged and the knob 91 is rotated, the auxiliary movable piece 7 slides to switch between the two directions. The groove 21a of the actuator 21 that engages the shaft 10a protruding from the upper sliding member 10 has a width d that is approximately large enough to receive the shaft 10a, and the shaft 10a is located in the direction indicated by the arrow in FIG. Make it possible to rotate around the center of the ball like B.

To rotate in this direction, rotate the knob 91 in the direction of arrow A in the figure, and move the operating lever 9 in the left-right direction in FIG. 1, or along a plane perpendicular to the page in FIG. Therefore, when the operating lever 9 is operated in this manner, the movable element 4 slides in the left-right direction in FIG. On the other hand, since this groove is configured to be open in the vertical direction as shown in FIG. 2, for example, as shown by arrow C in FIG. When tilted in the left-right direction, the operating lever 9 is tilted around point Q, and at the same time the shaft 10a is tilted as indicated by arrow D in the figure.

Therefore, when the operating lever 9 is moved in this direction, the movable piece 4 slides in the left-right direction in FIG. The operating lever consists of a knob 91 with the upper sliding member 10 formed at its lower end, and a shaft part 92 inserted into the knob 91.
2 has a D-cut flange 92a as shown in FIG. 8, and the D-cut flange 92a is iron-fitted to the D-cut recess of the Kaminuma motion part shown in FIG. , 91 are assembled, so when the knob 91 is rotated around its axis, the upper sliding member 10 rotates together with the shaft part 92.
As described above, the switch mechanism of the present invention has a four-way changeover switch section and a two-way changeover switch section disposed in one frame,
The four-way changeover switch section is switched by tilting an operation lever inserted into the frame from above, and the four-way changeover switch section is operated by rotating a knob of the operation lever around its axis. Since the structure is configured so that switching is performed by manual operation, it is possible to obtain a compact switch mechanism that can perform switching in four directions and switching in two directions with a single operating lever, and its operability is improved. can be shown to be good.
