Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a switch mechanism that alternately operates a plurality of push switches arranged in parallel by tilting the knob in two directions. This article relates to the best products for use in audio products etc. that are subject to restrictions.

(Prior Art) A conventional toggle switch mechanism for alternately operating a plurality of push switches arranged in parallel by a pinch operation is constructed as shown in FIGS. 1 and 2.

That is, as shown in FIG.
2 and 22' are arranged in parallel on the mounting plate 23, and the knob 21, which should be arranged on the front side, is formed in a substantially semicircular shape and is supported swingably around a fulcrum 24, with a protrusion at the tip. By tilting the operating section 21a thus constructed, the upper and lower operating sections 21b, 21'b of the rear straight section can be used to operate the push switch 22,
It is configured to alternately turn ON and OFF by pressing the pressing operation parts 22a and 22'a of 22'. In the device shown in FIG. 1, the fulcrum 24 of the knob 21 is located on the line C between the push switches 22 and 22'.

In addition, if the size, shape, placement position, etc. of the knob are restricted due to the placement space, etc., the second
As shown in the figure, the knob 25 is formed into a substantially "T" shape, and the lengths of the operating rods 26, 26' at both ends are made different so that the knob 25 can be operated eccentrically. Therefore, in the one shown in FIG.
The fulcrum 24 is located at the position line C' of the push switch 2
2 and the push switch 22'.

However, in the conventional device described above, the operating portions 21b, 21'b on the rear end side of the knobs 21, 25,
26a, 26'a push switch 22, 2
2', so the shape of the knob, the position of the fulcrum 24, the distance between the push switch 22 and the push switch 22', the distance between the knob and the push switch, etc. must be taken into consideration when arranging the switch. This makes the arrangement troublesome, and furthermore, it is not possible to ensure a sufficient stroke of the knob. In particular, in the case shown in FIG. 2, the fulcrum 24 of the knob 25 is placed offset from the center line between the two push switches 22, ₂₂ '. ′ is _different , and the ratio is directly expressed as the stroke ratio of the knob 25. Therefore, the strokes of the knobs for actuating the push switch 22 and the push switch 22' are different, resulting in difficulty in operability and in some cases, both the push switches 22, 22' cannot be operated properly.

(Purpose of the invention) The purpose of the invention is to eliminate the drawbacks of the conventional switch mechanism described above, and to provide a switch mechanism that does not have the risk of restricting the placement position of the knob and has good operability and operability. There is a particular thing.

(Structure of the invention) The switch mechanism of the invention is a switch mechanism in which a plurality of push switches arranged in parallel at the rear are actuated alternately by tilting a knob. A case having sloped parts formed at both corners; and a case arranged so as to be slidable in two directions within the case, and having sloped parts formed at both ends of the front side, and the sloped parts being the sloped parts at the inner corners of the case. a slider which is designed to swing by sliding along the axis to press the push operation part of the push switch individually and return to neutral by the return force of the push switch or a spring separately arranged in the case, and the slider at the rear end. and a knob arranged to slide the slider by tilting it via a fulcrum.

(Example) An example of the switch mechanism according to the present invention will be described based on FIG. 3.

In the figure, 1 and 1' are a plurality of push switches arranged in parallel on the mounting plate 2, and 3 is the push switch 1,
This case has a substantially U-shaped cross section and is placed on the mounting plate 2 so as to cover the mounting plate 1'.

Reference numeral 4 denotes a slider arranged to slide in two directions along the inner wall surface of the case 3, and by sliding in the two directions, the slider swings alternately to engage an operating portion 4a at the upper rear end and an operating section 4a at the lower rear end. Actuating part 4'
The push switches 1 and 1' are operated by pressing the push operation portions 1a and 1'a of the push switches 1 and 1', respectively, and are returned to neutral by the return force of the push switches 1 and 1'. The means for swinging the slider 4 is such that slope portions 5, 5 formed at both ends of the front side of the slider 4 are connected to the case 3.
Slope portions 3a, 3a formed at both inner corners of the
By sliding along the button, the push switch 1, 1' is swung in the direction of pressing the push switch 1, 1'.

Reference numeral 6 denotes a longitudinal knob having an engaging portion 7 at the rear end that engages with the slider 4, and the tip operating portion 6a can be tilted in two directions to rotate it around a fulcrum 8 provided at its center. The slider 4 is arranged to slide as shown in FIG.

The engaging portion 7 between the knob 6 and the slider 4 is configured as follows.

A recess 9 is formed at the rear end of the knob 6, and the rear end of the knob 6 is inserted into an engagement hole 11 provided in the slider 4 through an insertion hole 10 formed in the case 3. By this, they are engaged with each other. However, this engagement is not limited to the illustrated example, and other configurations may of course be used.

In the embodiment, the slider 4 is configured to be returned to neutral by the return force of the push operation parts 1a, 1'a of the push switches 1, 1'. You may also do so.

(Effect of the invention) According to the switch mechanism according to the present invention, in the switch mechanism in which a plurality of push switches arranged in parallel at the rear are actuated alternately by tilting the knob, the switch mechanism is arranged so as to cover the push switches. The case is arranged so as to be slidable in two directions within the case, and has sloped parts formed at both front ends, and the sloped parts are formed at the inside corners of the case. a slider that swings by sliding along the slope of the push switch and presses the push operation part of the push switch, and returns to neutral by the return force of the push switch or a spring separately arranged in the case; and a rear end. and a knob that has an engaging part that engages with the slider and is arranged so that the slider can be slid by tilting it through a fulcrum, and by sliding the knob in two directions. Since a plurality of push switches are operated individually via sliders, the placement positions of the knobs are not restricted by the placement positions of the push switches; for example, the knob holes to be formed in decorative panels, etc. can be selected at any position, making it extremely convenient as a switch mechanism in audio products, etc.

In addition, the operating stroke of the knob can be made large regardless of the arrangement position of the knob, and a plurality of push switches can be properly operated with the same operating stroke.
