Description

[Detailed Description of the Invention] "Industrial Application Field" This invention is a push switch that can be used in various electrical devices, for example, it is suitable for being installed in a car as a lighting switch for lighting equipment. .

"Prior Art" Two- and three-set push switches have been widely known. This type of switch has a variety of structures, but most have an interlocking relationship between them, so that when one switch is activated, the other switch is deactivated.

``Problems to be solved by the invention'' The above-mentioned multiple push switch has many advantages, such as allowing the switches to be centrally arranged and reducing installation space and labor. However, as mentioned above, there are interlocking relationships between the switches, which limits its use.

The present invention was developed in view of the above circumstances, and an object of the present invention is to develop a single-acting interlocking push switch that can freely perform interlocking operation between switches and independent operation of each switch.

"Means for Solving the Problems" Accordingly, the present invention includes a plurality of sliders having a returning force that advances toward the inside of the base by a pressing operation, and a plurality of sliders that are pivotally supported by the base fixing part and rotate toward each of the sliders. one interlocking member that applies a turning force to do so, an engaging member provided on each of the sliders, and engagement of each slider provided on this interlocking member that protrudes and locks the engaging member by the turning force of the interlocking member; A locking mechanism comprising a plurality of locking pins corresponding to the members and configured to lock the slider in the advanced position according to a preceding pressing operation of the slider and release the lock by a subsequent pressing operation, and a locking mechanism that moves the slider forward and backward. In the process, the interlocking member is pushed and the interlocking member is rotated against the turning force, thereby retracting the locking pin from the locking area of the engagement member and separately unlocking the locking mechanism. The present invention proposes a single-acting interlocking push switch, which is equipped with an interlocking mechanism including a pushing part and a passive part provided on the interlocking member, and switch mechanisms that move on each slider.

In addition, the present invention includes a movable chevron-shaped member whose apex is positioned between each of the sliders described above, and a contact portion provided on each slider that abuts the oblique portion of the chevron-shaped member during the advancement process of each slider. The feature is that it is equipped with a double-pressing prevention mechanism consisting of:

"Function" According to the present invention described above, each slider is alternately locked and released each time a pressing operation is performed.
The switch that operates each slider can be operated single-action, and when one of the sliders is locked in the advanced position and the other slider is pressed, the newly pressed slider will be activated. During the advancing process, the interlocking member is pushed against the turning force, so the locking pin provided on the interlocking member retreats from the locking area, and the preceding lock is released and the locked At the same time, the slider that was previously pressed returns to its original position, and the newly pressed slider is moved forward, and the switches that operate these sliders are switched in conjunction with each other.

"Example" Next, embodiments of the present invention will be described with reference to the drawings.

The illustrated embodiment is a three-series single-acting interlocking push switch implemented as a switch for controlling a lighting device of an automobile, and FIG. 1 is a longitudinal sectional front view of the switch taken along line A-A in FIG. Fig. 2 is a cross-sectional bottom view of the switch taken along line B-B in Fig. 1, and Fig. 3 is a cross-sectional bottom view taken along line B-B in Fig. 2.
FIG. 4 is a longitudinal sectional front view similar to FIG. 1 taken along line C, and FIG. 4 is a longitudinal sectional side view of the switch taken along line DD in FIG. 2.

In these figures, reference numeral 1 denotes a switch base whose internal space is divided into a front stage and a rear stage (upper and lower stages in Figure 2) by a partition 1a. is secured with screws.

3.4.5 is an operation knob screwed to the rear of the slider 6.7.8 which is slidably attached to the switch base l.
A window hole is formed in the front of each of these, and graphic display plates 3a, 4a, 5a suitably indicating the role of each switch are attached to these window holes.

The graphic display boards 3a, 4a, and 5a are light guides (lenses) each having an arm extending near each window hole of the operation knob.
When receiving the light from a light source 10 guided by 9, the graphic display stands out optically.

The light guide 9 and the light source 10 are integrally provided on the cover plate 2, and by screwing the cover plate 2, the light guide 9 and the light source 10 are incorporated into the front space of the switch base l.

The sliders 6, 7, and 8 are slide blocks of the same shape, and a part of these slide blocks protrudes outside the base through a window hole provided in the left side wall of the switch base l, and the above-mentioned operation knob is screwed to the slide block.

The slider 6.7.8 is shown in an enlarged perspective view in FIG. 5 and in an enlarged sectional view in FIG. Although only the slider 6 is shown in these figures, since the other sliders 7 and 8 have the same shape, the same parts are given the same subscripts.

As shown in the figure, the slider 6 is formed by integrally forming a plate part 6b with guide protrusions 6a on the left and right sides (top and bottom in FIG. 1) and a thick square part 6C to which the operation knob 3 is attached.
Furthermore, a boundary portion 6 protrudes symmetrically on the surface of the plate portion 6b.
d is integrally formed.

This boundary portion 6d is for preventing double pressing, and has an inclined portion at its tip, and together with a chevron plate to be described later, constitutes a double pressing prevention mechanism. The chevron-shaped raised portion 6e provided at one boundary portion 6d is for releasing the lock ta structure, which will be described later.

The thick part provided at the lower end of the plate part 6b is a terminal receiver 6f,
It is provided with terminal holes for equipping electrical contacts 11a, llb in a known manner. In addition, the electrical contact piece 11
a, llb are equipped so as to be constantly pressed downward in FIG. 5 by a coil spring 12.

In the plate portion 6b of the slider 6, a shaft hole 6g for pivotally supporting a heart-shaped cam plate 13, which will be described later, is provided near the tip of a boundary portion 6d. It is rotatably supported, and a window hole 6h is formed at the base of the two boundary parts 6d, into which the tongue piece 13a of the heart-shaped cam plate 13 is movably inserted. This allows the heart-shaped cam plate 13 to swing stably.

Each slider 6.7.8 formed as described above is connected to the first
It is attached so that it can be moved laterally in the figure.

That is, in the lower space of the switch base, the guide walls 1b and ICs shown in FIGS. A guide groove is formed on the inside of the lower surface. and,
The guide protrusions 6a, 7a, 8a of the slider 6.7.8 are fitted into these guide grooves, and the slider 6 is placed between the upper surface of the switch base 1 and the guide wall 1b.
The slider 7 is placed between the guide walls 1b and lc, and the slider 8
are installed between the guide wall 1c and the lower surface of the switch base 1.

The slider 6.7.8 installed as described above is subjected to a force of movement in the left direction in FIG.
Guide protrusion 6a of slider 6.7.8, ? The end portions a and 8a are resting at a position where they are in contact with the inner surface of the left side wall of the switch base 1.

Further, as already mentioned, the slider 6.7.8 is equipped with electrical contact pieces 11a and llb, and these contact pieces 1
1a and llb are pressed against the surface of a terminal board 17 fixed to the rear part (lower side in FIG. 2) of the switch base 1 by the expanding force of the coil spring 12 to form a slide switch.

Heart-shaped cam plate 13 pivoted on each slider 6.7.8
．． 14.15 are shown enlarged in FIGS. 7 and 8. Note that the heart-shaped cam plate 13 is shown in these figures.
However, since the other heart-shaped cam plates 14 and 15 have the same structure, the same parts will not be shown with the same subscripts.

As shown in the figure, the bar 1-shaped cam plate 13 is rotatably attached to the slider 6 by a shaft pin 18 inserted into the shaft hole 13b, and a tongue piece 13a provided at the tip thereof is attached to the window hole 6h of the slider 6. The heart-shaped cam plate 13 is movably inserted into the slider 6, and the heart-shaped cam plate 13 swings about the shaft pin 18 between the two boundary parts 6d of the slider 6. In addition,
Another heart-shaped cam plate 14.15 is similarly pivoted to each slider 7.8 by an axle pin 19.20.

A locking pin 24, which will be described later, slides against the cam groove of the heart-shaped cam plate 13, but when the slider 6 is retreating, it is at position a, and when it advances to the deepest part, it is at position a-b-c.
It moves to the C position along the P path, and then when the pressing force of the slider 6 is released, it moves from the C position to the d position and enters the locked state.

In this locked state, when the slider 6 is pushed again to advance to the deepest part, the lock is released by moving from the d position to the C position, and then, by releasing the pushing force, the Q of d-r-a The slider 6 is returned to the position a along the route.

The locking pin 24 will be described later, but this locking pin 24
Since the heart-shaped cam plate 13 is configured to retreat in a direction perpendicular to the plate surface of the heart-shaped cam plate 13, when moving along the above-mentioned path P, the heart-shaped cam plate 13 is once swung counterclockwise in FIG. After that, it swings clockwise.

Conversely, when moving along the Q path, the heart-shaped cam plate 13 swings clockwise in FIG. 1 and then swings counterclockwise.

Further, the locking portion 13C of the heart-shaped cam plate 13 is provided with a stepped surface 13d that is stepped down at one shoulder portion, and when the locking pin 24 is retracted at the d position (locked position), the above-mentioned It passes over the stepped surface 13d to move from the d position to the a position, and unlocking is performed separately on the R path.

On the other hand, the locking pin 24 described above is fixed to the pivot plate 21 shown in FIGS. 1 and 2.

The swivel plate 2I is a quadrilateral plate that is rotatably supported on the shaft 22. In normal conditions, the slider 6.7 is moved by a coil spring 23 wound around the lower part of the shaft 22.
．． 8 (turning force in the counterclockwise direction in Fig. 2).

This rotating plate 21 is provided with a bent pivot support 21a at the upper and lower parts of the right side, and a pivot rod 22 is pivotally inserted into this pivot support 21.11. Further, the shaft rod 22 is in the shape of a round bar, and its upper and lower shaft ends are supported by a bearing 2a integrated with the cover plate 2.

As mentioned above, the heart-shaped cam plates 13, 14.
15 Three locking pins 24 protruding toward each a position
．． 25 and 26 are fixed, and under normal conditions, these locking pins protrude into the cam groove at position a.

Further, on the left-side plate surface of the rotating plate 21, embossed chevron-shaped protrusions 27, 28, 29 are formed on each slider 6.7.
It is formed to protrude rearward (downward in FIG. 2) so as to be in contact with the oblique portions of the chevron-shaped raised portions 6e, 7e, and 8e of No.8.

Normally, the left wound part of the chevron protrusion 27, 28, 29 is in contact with the right oblique part of the chevron protrusion 6e, 7e, 8e, and as each slider 6.7.8 advances and retreats, these chevrons The ridge is climbed over, and the pivot plate 21 is then pivoted away from each slider 6.7.8, ie clockwise in FIG. 2.

The chevron plates 30 and 31, whose tops are located between the sliders 6 and 7 and between the sliders 7 and 8 by passing the shaft rod 22, prevent the sliders from being pressed twice. It is.

These chevron-shaped plates 30, 31 are movable relative to the shaft rod 22, and their right side portions are arranged so as to move within an elongated hole 2b provided in the cover plate 2 and parallel to the shaft rod 22.

When each of the sliders 6.7.8 is advanced individually, this chevron plate 30.31 is pushed by the slope at the tip of the border, allowing the slider to advance to the deepest part, but at the same time two or more When the slider is pressed,
As each slider moves forward, the inclined parts at the tips of the boundaries provided on these sliders collide with the tops at the same time, so the chevron plate 30 or 31 cannot move, and each slider maintains the position shown in the figure. work to prevent the advance of It should be noted that since the prevention of advance of the chevron plates 30 and 31 is carried out during the advance process of the slider, the slide switch that drives the slider is not switched during this prevention stage.

Next, the operation of the above-mentioned single-acting interlocking push switch will be explained with reference to the operation process diagrams of FIG. 9, FIG. 1O, and FIG. 11.

When not operated, each slider 6, 7, 8 returns to its original position under the pressure expansion action of the coil spring 16 and is in the state shown in FIGS. 1 and 2. Therefore, the chevron-shaped projections 27, 28, 29 of the rotating plate 21 are in contact with the chevron-shaped protrusions 6e, 7e, 8e of each slider 6.7.8 as shown in FIG. The plate 21 is pivoted counterclockwise in the figure, and each locking pin 24, 25, 26 is connected to the heart-shaped cam plate 1.
It has entered position a in 3.14.15.

FIG. 9 is a partially enlarged view of the slider 6 showing the above-described stationary operation process, in which the electrical contact piece 11a,
llb is in the first switch state. Note that the other sliders 7.8 are in the same operating state.

Now, assuming that a pressing operation force is applied to the operating knob 3, as the slider 6 advances, its chevron-shaped protrusion 6e advances while pushing up the chevron-shaped protrusion 27, resulting in the operation process shown in FIG.

In this operation process, the locking pin 24 not only moves away from the position a of the cam groove, but also floats up in a direction perpendicular to the plate surface of the heart-shaped cam plate 13.

However, this bottle 24 does not escape from the cam groove.

As the slider 6 continues to advance, the chevron-shaped protrusion 2
7 climbs over the chevron-shaped protuberance 6e, and the locking pin 24 plunges back into contact with the bottom of the cam groove due to the clockwise turning force of the rotating plate 21. When the slider 6 advances further and reaches the deepest position, the locking pin 24 24 passes through the cam groove and reaches position C.

Here, if the pressing force 1 is released, the locking pin 24 moves to the d position of the cam groove as the slider 6 retreats, and the locking pin 24 passing through the path P locks the lock shown in FIG. 11. It becomes a working process. In this state, the electrical contact piece 11a
, llb slide on the terminal board 17 and switch to the second switch state.

When the operation knob 3 is pressed again in the above-mentioned open/tuck state, the locking pin 24 moves through the cam groove to the C position with the slight advancement of the slider 6, so the pressing operation force is released here. For example, since the locking pin 24 passes through the Q path, the slider 6 moves backward under the pressure expansion action of the coil spring 16 and immediately returns to the position shown in FIGS. 1 and 2.
The slide switch changes from the second switch state to the first switch state. In this return operation, the chevron-shaped raised portion 6e abuts against the chevron-shaped protrusion 27, so that the turning plate 21 is once turned counterclockwise in the same manner as in FIG. 10.

The above-described independent operation is not limited to the slider 6, but also applies to the sliders 7.8.

Next, assuming that the operating knob 4 is pressed while the slider 6 is locked and in the operating process shown in FIG. Therefore, the rotating plate 21 is rotated counterclockwise against the rotating force in the same manner as in FIG. As a result, the locking pin 24 moves from the d position to the a position through the R path of the heart-shaped cam plate 13, and the slider 6 is unlocked.
The slider 6 returns to its original position under the pressure expanding action of the coil spring 16.

As the slider 7 continues to advance, the locking pin 25 enters into the d position of the heart-shaped cam plate 14 and is locked in the same manner as described above. In this locked state, the slide switch driven by the slider 7 switches from the first switch state to the second switch state.

This interlocking operation is performed between each slider, and when one slider is locked, by advancing any other slider, the locked slider can be returned to its original state.

"Effects of the Invention" As described above, in the single-acting interlocking push switch according to the present invention, each switch mechanism can be operated independently without being related to other switch mechanisms, and any one of the switch mechanisms can be operated independently.・By operating another switch mechanism when the 7-chi mechanism is in the operating state,
The previously operated switch mechanism can be automatically restored and other switch mechanisms can be set to operate anew.

Further, according to the present invention, the plurality of sliders and the locking members such as heart-shaped cam plates provided on each of these sliders have the same structure,
Furthermore, since the plurality of locking pins that are engaged with the locking portions are fixed to one rotating member, a multifunctional push switch can be provided with high productivity and at low cost.

Furthermore, in the present invention, a double push prevention mechanism is constructed by a movable chevron-shaped member and a contact portion provided on each slider that abuts the oblique portion of the chevron-shaped member during the advancing process of the slider, so that the mechanism is simple. By incorporating this, it is possible to prevent harmful effects caused by simultaneous operations.
