Description

[Detailed description of the invention] The present invention is a device in which a plurality of units that operate two loads (for example, a motor or a solenoid) in a related manner performs a set of functions, such as an electric fender mirror for an automobile, a magic hand, or a machine tool. In remote control of machinery, etc., a multi-directional switching switch that allows you to selectively switch the controlled unit by rotating a single switch lever, and also allows you to operate the controlled unit in relation to the movement of the switch lever when you tilt it. It is related to.

Conventionally, in the remote control of an automobile fender mirror having the circuit shown in FIG. 1, for example, an insulating part 34 and upper and lower hemispherical parts 33 attached above and below the insulating part 34 are used, as shown in FIGS. 3 and 4. , 35, by bringing the contacts 39 and 44 into contact with each other, the hemispherical portion 3
A plurality of contacts 40, 41, 42, 43 are provided, each of which has a potential applied thereto to form two poles, and which contacts the insulator 34 at the neutral position of the operating lever 31 attached to the upper hemisphere 33. , when the lever 31 is operated in the directions of arrows A, B, C, and D shown in FIG.
0, 41, 42, and 43 are configured to come into contact as shown in the connection table shown in FIG. 2 to drive the fender mirror in the direction desired by the driver.

However, car fender mirrors have one on each side.
There are two switches in total, so the conventional switch is the third switch.
As shown in Figures 4 and 4, the switch is integrated, but since it actually has two switches, it has many parts and is expensive.Moreover, not only does the switch become bulky, but it also makes it difficult for the driver to When trying to change the direction of the fender mirror, the driver had to keep his eyes on the road ahead, so he was unable to turn his attention to the switch lever, which led to him selecting the wrong switch lever (left or right) and making an erroneous operation. .

The present invention provides a lever-type multi-directional changeover switch that has a small number of parts, is small, inexpensive, and prevents erroneous operation.

The fifth example is based on an example in which the configuration of the present invention is adopted as a controlled unit in an automobile fender mirror.
This will be explained using FIGS. In FIG. 6, the upper hemisphere part 3 and the lower hemisphere part 5 are insulated by the first insulating part 4, and are integrated into one three-part rotating ball 23.
is formed. On this spherical surface, two sets of long circular grooves L, R, 21, 22 are provided approximately parallel to the lever 19, and the ball 6 is pressed into the grooves by a spring 7 so that the lever 19 is centered. Moderation is given to the rotation of the rotating ball 23. Further, the upper hemisphere 3 is in contact with the first contact 10 fixed to the upper case 2, and the lower hemisphere 5 is in contact with the 10th contactor 10 fixed to the upper case 2.
They are in contact with the second contactor 14 shown in FIGS. 1 and 11, respectively, and are given potentials to form two positive and negative poles. Further, the upper hemisphere portion 3 and the lower hemisphere portion 5 are provided with a notch 25 serving as a second insulator. A recess 24 is provided in the lower part of the lower hemisphere 5, and a return spring 9 is provided.
When the driver releases the lever 19 after operating the lever 19, the lever 19 automatically returns to the neutral position. This plunger 8 also has the function of holding the rotating ball 23 by pressing the rotating ball 23 against the spherical surface inside the upper case 2.

When the lever 19 is in the neutral position in FIG. 10, the third contact 1 is in contact with the first insulator 4.
A fourth contact 17 and a fifth contact 18 are provided adjacent to each other 180 degrees opposite the contact 16 and the third contact 1 as shown in FIG.
5 is connected to one end of the first load (in this case, one solenoid SL and SR each on the left and right) of the left and right fender mirrors, and the third contact 16 is connected to the second load 4 on each of the left and right sides (in this case, one solenoid each on the left and right). motor of

When the lever 19 is released, the plunger 8 pressed by the return spring 9 automatically returns the lever 19 to the neutral position. Of course, the fender mirror remains in its original orientation (upward in this case).

Next, when the lever 19 is tilted in the H direction in FIGS. 10 and 11, the third contact 15 is insulated, the third contact 16 comes into contact with the upper hemispherical surface 3, and the fifth
The fourth contact 18 is in contact with the lower hemispherical surface 5, and the fourth contact 17 is insulated. In this state, the 12th
The first load (SR) of the right fender mirror in the figure does not operate, and the second load (MR) rotates, for example, counterclockwise, and correspondingly, the right fender mirror (not shown) gradually moves to the left. Change the tilt.

Next, when the lever 19 is tilted in the direction G, the third contacts 15 and 16 come into contact with the upper hemispherical surface 3, the fifth contact 18 comes into contact with the lower hemispherical surface 5, and the fourth contact 17 is insulated.

Next, when the lever 19 is tilted in the F direction, the third contact 15 is insulated, the contact 16 is in contact with the lower hemisphere 5, the fifth contact 18 is in contact with the upper hemisphere 3, and the fourth contact 17 is in contact with the upper hemisphere 3. is insulated. In this state, the first load (SR) of the right fender mirror in FIG. 12 does not operate, and the second load (MR) rotates, for example, clockwise, and correspondingly, the right fender mirror (not shown) rotates. Change the tilt to the right.

Next, when the driver operates the knob 1 and rotates the rotary ball 23 to the left about the lever 19 by about 20 degrees, the balls 6 and 6' will move into the oblong groove L2 as shown in FIG.
1 and 21', and now the condition changes to operating the left fender mirror, and the fifth contact 18 of the right fender mirror is completely insulated by the notch 25. In this state, for example, if the lever 19 is tilted in the direction of arrow F in FIG.
Since the third contact 15 and the fifth contact 18 are insulated, only the second load (ML) of the left fender mirror rotates clockwise in FIG. The fender mirror gradually tilts to the right.

Note that when you release your hand from the lever 19, the return spring 9
The lever 19 automatically returns to the neutral position by the action of the plunger 8 that is pressed. Next, when the lever 19 is tilted in the E, H, and G directions, the left fender mirror changes its tilt in the upward, leftward, and downward directions, but the way to connect the third contacts 15 and 16 is , is the same as the case of the right fender mirror described above.

FIG. 13 shows a connection table of the embodiment of the present invention. The left and right fender mirrors can be switched either when the lever 19 is in the neutral position or when the fender mirror is operated by tilting the lever 19.

According to the multi-directional switch of the present invention, multiple devices can be remotely controlled with one lever, so if you select the wrong lever and operate it incorrectly, or change the grip of multiple levers each time you switch the controlled unit. It is not necessary, so it is easy to operate, and
It has great practical value and has very large effects such as a small number of parts, small size, and low cost.
