Description

[Detailed Description of the Invention] The present invention can be used for remote control of equipment in which a plurality of units that operate two loads in a related manner performs a set of functions, such as electric fender mirrors for automobiles and magic hands. This invention relates to a multi-directional changeover switch configured so that when a switch lever is tilted, a controlled device can be operated in relation to the movement of the switch lever.

Conventionally, for example, as shown in FIGS. 1 and 2, an insulating part 3 provided on the equator and conductive hemispherical parts 1 and 2 provided above and below the insulating part 3 form a sphere, and a contact 13 .
A plurality of contacts 9, 10, 11, 12 are provided which contact the insulating part 3 at a neutral position, and a contact 13 which contacts the upper hemisphere part 1 and a contact part which contacts the lower hemisphere part 2 in any state. A contactor 14 is provided. In this type of switch, a contact 9 that tilts the operating lever 4 in the direction of arrow N shown in FIG.
A positive potential is applied to a load such as a motor (not shown) connected between the contacts 9 and 10 in contact with the contactors 9 and 10, and the load rotates in the positive direction. Furthermore, when the operating lever 4 is tilted in the direction opposite to the direction of the arrow N in FIG.
A negative potential is applied to the load such as a motor, causing it to rotate in the opposite direction.

However, for example, in the remote control of electric fender mirrors for automobiles, there are two mirrors, one on the left and one on the left, so conventionally this type of switch was integrated as shown in Figures 1 and 2. In practice, there were two switches, which required a large number of parts and was expensive, and the switch itself was large.Furthermore, when the driver of the car tried to change the direction of the fender mirror while driving, the driver could not move forward. Because I had to keep looking at the switch lever, I was unable to pay attention to the switch lever, and sometimes I made a mistake in selecting the left and right switch levers and operated them incorrectly.

Furthermore, in the conventional switch, since the upper hemisphere 1 to which a potential is applied is exposed through the opening 16 in FIG. or
There was a risk of contact with other conductors or lead wires, causing a shoot.

The object of the present invention is to provide a safe multi-directional changeover switch that is free from erroneous operation, has excellent operability, has a small number of parts, is small and inexpensive, and has no shot or the like.

Figures 3 to 3 are based on an example in which the configuration of the present invention is applied to an electric vehicle fender mirror switch.
It is shown in FIG. In FIG. 7, the movable contact pieces 23 and 24 on the equator and the upper and lower hemispherical insulating parts 21 and 22
The parts are integrated to form a sphere 20 shown in FIG. 3, and a plunger 27 biased by a spring 29 from the lower case 26 side comes into contact with a recess 28 provided at the bottom of this sphere 20, and the sphere 20 is pushed into the upper case 25.
The sphere 20 is held by pressing against it, and when the driver operates the control lever in any direction and then releases his/her hand, the control lever automatically returns to the neutral position.

As shown in FIG. 4, on the equator of the sphere 20, there are first grooves 40, 40' and second grooves 41, each having an oblong shape.
41', and when the driver turns the operating lever 32 to the left together with the knob 33 in FIG.
The balls 30, 30' accommodated in the springs 31, 31' are in contact with the first grooves 40, 40', and when the operating lever 32 is rotated to the right, the balls 30, 30' are biased by the springs 31, 31'. Since it comes into contact with the second grooves 41, 41', it is configured to provide moderation when the sphere 20 is rotated.

The movable contact piece 24 on the equator described above in FIGS. 8 and 9 has a slightly protruding part called a switching part 24a, and the contacts 38 and 39 are attached to the lower case 26 as a pair. The tips of the contacts 38 and 39 are located around the sphere 20 and are always in contact with the surface of the sphere 20. When the operating lever 32 is rotated counterclockwise about the shaft as shown in FIG. 8, the contact 38 comes into contact with the movable contact piece 24, and the contact 39 does not come into contact with it and is insulated. On the other hand, the 9th
When rotated clockwise as shown in the figure, the mounting positions of the contacts 38 and 39 are changed so that the contact 38 is separated from the movable contact piece 24 and is insulated, and the contact 39 comes into contact with the switching part 24a of the movable contact piece 24. It's decided. The switching state of the contacts 38 and 39 can be clearly known by the orientation of the protrusion 33a of the knob 33 attached to the tip of the lever 32, as shown in FIG.

The lower case 26 further includes contacts 34, 34',
35, 35', 36, and 37 are located around the spherical body 20, and are attached so that their tips are in contact with the surface of the spherical body 20, but the contacts 34 and 35 and 34' and 35' are When the operating lever 32 is in the neutral state, the contacts 34 and 35 are located below and above the movable contact piece 24 on the equator, respectively, and the contacts 34' and 35' are located above the movable contact piece 23 on the equator. located at the bottom and top respectively.
The contact 36 is always in contact with the movable contact piece 23, and the contact 37 is in contact with the notch hole of the movable contact piece 23.

The operation will be explained below. When the embodiment of the present invention is applied to a switch for an electric fender mirror for automobiles (hereinafter referred to as mirror), the circuit is
It will look like Figure 0. contacts 34, 34' and 35,
35' constitutes two poles connected to the battery 43, the contact 37 is connected to one end of the first load (solenoid) SL and SR of the left and right mirrors, and the contact 36 is connected to the second load (motor) ML and MR. The contactor 38 is connected to the other end of the first load SL and the other end of the second load ML of the left mirror, and the contactor 39 is connected to the other end of the first load SR and the second load MR of the right mirror. connected to the other end.

First, as shown in FIG. 8, when the operating lever 32 is rotated to the left, the contact 38 comes into contact with the movable contact piece 24. As shown in FIG. When the operating lever 32 is tilted in the direction of arrow A from this state, the movable contact piece 24 will be moved to the contacts 38, 34, the movable contact piece 23 will be moved to the contacts 36, 35',
37 respectively, and the first load of the left mirror
While energizing SL, the second load ML is rotated, for example, clockwise. At this time, the left mirror gradually turns upward. When the lever 32 is released, the plunger 27 automatically returns to the neutral position as shown in FIG. 3 by the action of the plunger 27 biased by the spring 29. Note that the mirror continues to face upward.

Next, when the operating lever 32 is tilted in the direction B, the movable contact piece 24 contacts the contacts 38, 34, the movable contact piece 23 contacts the contacts 36, 35', and the second
Rotate the load ML clockwise. Since the first load SL is not energized, the left mirror gradually changes direction to the right.

Next, when the operating lever 32 is tilted in the C direction, the movable contact piece 24 contacts the contacts 38, 35, and the movable contact piece 23 contacts the contacts 36, 37, 34', energizing the first load SL of the left mirror. At the same time, the second load ML is rotated counterclockwise, so that the left mirror gradually changes direction downward.

Next, when the operating lever 32 is tilted in the direction D, the movable contact piece 24 contacts the contacts 38 and 35, and the movable contact piece 23 contacts the contacts 36 and 34', and the first load SL is not energized and the first load SL is not energized. Since the load ML of No. 2 is rotated counterclockwise, the left mirror gradually changes direction to the left.

Note that the first
The load (solenoid) switches the drive direction of the second load (motor) vertically or horizontally depending on the selection of the gears that engage, and the second load (motor) The mirror is moved by driving a gear in the forward or reverse direction.

Note that when the operating lever 32 is released, the plunger 27 automatically returns to the neutral position due to the action of the plunger 27 biased by the spring 29 in FIG.

Next, when the driver operates the knob and rotates the operating lever 32 approximately 30 degrees to the right, the groove 40, as shown in FIG.
The balls 30, 30', which had been fitted into the grooves 40', fit into the grooves 41, 41', and as shown in FIG. 9, the contact 39 comes into contact with the movable contact piece 24, and the contact 38 is insulated. In this state, for example, the operating lever 3
2 in direction A, this time the first mirror on the right side
The load SR and the second load MR operate in the same manner as described above to change the direction of the mirror upward. When the operating lever 32 is tilted in the directions of arrows A to D in this way, the respective contacts come into contact as shown in the connection table of FIG. 11, and the left and right mirrors are tilted in the respective directions.

In addition, switching between the left and right mirrors can be easily performed by simply rotating the knob 33 by about 30 degrees, whether the operating lever 32 is in the neutral state or the operating lever 32 is tilted and the mirror is operating. The opening 42 in FIG. 3 is always covered by the upper hemispherical insulating part 21 so that the conductor does not appear, so there is no danger of shoots or the like.

Another embodiment is shown in Fig. 12 and Fig. 13. This embodiment is a remote control switch for a mirror composed of two motors as shown in the circuit diagram of Fig. 14. As shown in Fig. 12, four movable contact pieces 53 to 56 are provided on the equator of a sphere, and contacts 57 to 64 are provided to contact and separate them.
In FIG. 13, when the operating lever 69 is rotated, the springs 71, 71'
The balls 70, 70' biased toward the first position on the equator.
The first groove 67, 67' and the second groove 68, 68' are switched to abut against each other, and at the same time the contacts in contact with the four movable contact pieces 53 to 56 are switched. When the operating lever 69 is tilted in each direction of the arrows E to L shown in Fig. 12, the contacts come into contact as shown in the connection table in Fig. 15 to form the respective circuits and tilt the mirror (not shown) in the specified direction. Although this embodiment has been described with respect to a switch for operating two devices, it goes without saying that three or more devices can be operated by increasing the number of grooves 67, 68 and changing the arrangement of the contacts.

According to the multi-directional switch of the present invention, multiple devices can be remotely controlled with one operating lever, so there is no need to take the trouble of holding multiple operating levers, and there is no need to worry about selecting the wrong operating lever and operating it incorrectly. It has great practical value as it has advantages such as being easy to operate, having a small number of parts, being small and low cost, and being safe as there is no shot or the like.
