Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a joystick for selecting and controlling a plurality of switches.

[Prior Art] In-vehicle audio equipment such as car stereos, component stereos used at home, karaoke, etc. are becoming more and more multi-functional, and the number of function switches and the like for selecting the functions is increasing. There is.

Therefore, functions are selected and switched using a large number of push buttons arranged in parallel in the horizontal or vertical direction.

However, in-vehicle electronic devices, such as car stereos, are manufactured to fit dimensions according to the DIN standard for openings in vehicles, and therefore front panel space is limited.

Providing other types of changeover switches individually on that panel is space-constrained, so
It's getting difficult.

On the other hand, in order to save space and select and control a plurality of switches, a multi-directional changeover switch is known that uses a joystick that can be freely operated in multiple directions.

FIG. 3 shows an example of a changeover switch 31 using the joystick 30.
By swinging the lever 32 in the left and right directions, switches 33, 34,
35, 36 switch shafts 33a, 34a,
The switch is turned on by pushing either one of the switches 35a and 36a.

That is, the joystick 31 is connected to a socket 37 provided on a board or base (not shown).
A lever rear end portion 38 formed in a spherical shape is fitted into the lever, and the lever is swung in four directions, up, down, left and right, using this portion as a swinging fulcrum.

By the way, Switch 33, 34, 35, 36
The shafts of the switches can be pushed by the levers 32 on the printed wiring board 39, and the switches are disposed at diagonal positions whose phases differ by 90 degrees.

Therefore, when the joystick 31 is swung in any direction, for example to the left, the lever 32
The switch shaft 33a of the switch 33
is pressed to turn on, and then the switch shaft is moved back by the elastic member built into the switch, and the lever 32 is returned to its original position.

The above operation is performed in the same way in the other three directions, and a single lever selects and controls a plurality of switches.

[Problems with the Prior Art] The conventional example selects and controls four switches in a small amount of space, but it merely selects the switches and cannot accommodate further multi-functions.

[Means for Solving the Problems] The present invention provides a joint member such as a universal spring or a universal joint at the swinging fulcrum portion of the operating rod in a joystick that selects and controls a plurality of switches. This is a joystick structure characterized in that a volume member consisting of a variable resistor made of carbon, metal, or semiconductor is disposed at the other end.

[Function] The joystick of the present invention is capable of swinging the operating rod in the X-axis and Y-axis directions on the front side using the joint member portion as a fulcrum, but from the fulcrum,
It functions so as not to swing, and on the other hand, by pressing each switch shaft arranged on the extension of the operating rod with the operating rod during the swinging, an arbitrary switch is selected and the equipment is controlled.

Furthermore, by rotating the operating rod clockwise or counterclockwise, the volume of a car stereo or the like can be adjusted.

[Example] The present invention will be explained based on an illustrated example. FIG. 1 is a perspective view showing one embodiment of the present invention, and FIG. 2 is a perspective view showing another embodiment of the joint member portion.

In the joystick 1 of the present invention, a spherical operating part 3 is formed at the tip of an operating rod 2, and is operated by grasping with fingers.On the other hand, in the middle part of the operating rod 2, a flexible spring 4a or a second Joint members such as the universal joint 4b shown in the figure are provided.

Further, the other end of the joint member, that is, the terminal end of the operating rod 2, is directly connected or connected to the rotating shaft of a variable resistor 5 used for adjusting the volume or the like. The resistor is a carbon-based or metal-based one whose resistance value is determined by mechanical contact with a slider that slides on the surface of the resistor by rotation of the shaft, or
It is a semiconductor type that does not rely on mechanical contact.

Further, a multi-directional changeover switch S is provided with a joystick 1 having the variable resistor 5 at one end.
An opening that allows the operating rod 2 to swing is formed in a printed wiring board 6 disposed at the rear of an escutcheon (not shown), and is equidistant from the center of the opening, and is positioned vertically and horizontally. switch 7, 8,
9, 10 are arranged, and switches 7, 8,
switch shafts 7a, 8a, 9a, 10 protruding from the front surfaces of the switches 9, 10 and formed to be freely pushable;
The tip of a is arranged to face the center of the opening.

Therefore, the joystick of the present invention is capable of selecting each switch by grasping the operating portion and swinging the operating rod vertically and horizontally using the joint member as a fulcrum, and turning the switch ON and OFF. be.

In addition, when the operating section is rotated clockwise or counterclockwise, the volume and the like can be adjusted.

By the way, the volume member such as the variable resistor can be turned on by pushing the operating rod.
Functionality can be further improved by using push-on volume members that can be turned on and off.

[Effects of the invention] The present invention uses a joystick for multi-directional switching, making it possible to move the operating rod in up, down, left and right directions, as well as adjusting the volume by rotating the joystick itself clockwise or counterclockwise. This allows for multi-functionality without requiring space, even in a narrow and limited space.

Furthermore, as described above, if the volume member itself is made to have a function that can be selected by operating an operating lever toward the front or the back, it is possible to further increase the number of functions.
