Description

[Detailed description of the invention] The present invention relates to an interlocking pushbutton switch in which multiple pushbutton switches are arranged in two stages, and in particular, are arranged in two stages. This invention relates to a connection mechanism for operating multiple pushbutton switches in conjunction with each other.

The interlocking mechanism in each multiple push button switch is generally constructed as shown in FIG.

Reference numeral 1 denotes a locking plate having a raised tongue piece 1a, which is biased in the direction of arrow A by a spring (not shown).

Reference numeral 2 denotes an operating rod that is biased in the direction of arrow C by a return spring, and a sawtooth cam groove 2a is provided on one side of the operating rod.

The locking plate 1 locks the plurality of operating rods 2 at the switch-on position or the switch-off position by engaging the tongue piece 1a with the cam groove 2a.

Now, when any operating rod 2 is pressed, the locking plate 1 comes into contact with the slope 2b of the cam groove 2a and moves in the direction of arrow B, so the operating rod 2 that was in the on position is no longer engaged with the tongue piece 1a. is released and returns to the off position.

The newly pressed operating rod 2 is then locked in the on position.

The present invention aims to provide a connection mechanism that can easily achieve reliable interlocking operation between both multiple pushbutton switches when multiple pushbutton switches that perform such interlocking operations are arranged side by side in two stages. It is.

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 2 is a front view of the interlocking pushbutton switch according to the present invention, Fig. 3 is a side view thereof, and Fig. 4 is a perspective view from the rear.
FIG. 5 is an exploded perspective view of the main parts.

In FIGS. 2 to 5, reference numeral 3 denotes a frame body having a substantially U-shaped cross section to which a plurality of pushbutton switches 4 are fixed, and a locking plate 5 for interlocking each pushbutton switch 4 is loosely attached to the inner bottom surface of the frame body. The frame body 3, the locking plate 5, and the plurality of pushbutton switches 4 constitute a set of multiple pushbutton switches.

Similarly, the frame 3', the locking plate 5', and the plurality of pushbutton switches 4' constitute another set of multiple pushbutton switches.

6 and 6' are sliders of the push button switches 4 and 4', respectively.

Reference numeral 7 denotes a round rod-shaped support with a female thread cut at the end, and screws 9 are screwed into both ends to connect and fix the two frames 3 and 3'.

8 is a cylindrical connector, which has a protrusion 8a on the side.
It is rotatably attached to one of the pillars 7.

Notches 5a and 5 provided at the ends of the locking plates 5 and 5'
The protrusion 8a of the connector 8 is engaged with both 'a.

Note that instead of the connector 8 having one protrusion 8a, two protrusions 9a and 9b on opposite sides as shown in FIG.
You may use the connector 9 which has.

At this time, the two locking plates can be driven in opposite directions.

In the interlocking push button switch configured as described above, when any slider 6 or 6' is pressed, the respective locking plates 5 and 5' are connected by rotatable connectors, so that they are simultaneously driven. be done.

For this purpose, pushbutton switches 4 and 4 are fixed to separate frames.
′ operate in conjunction with each other.

As described above, in the interlocking pushbutton switch according to the present invention, the connector is rotatably attached to the support that connects the frame bodies of two sets of multiple pushbutton switches, and the protrusion provided on the connector is connected to the respective latches. Since it only needs to be engaged with the plate, there are few components, and assembly is extremely simple, and reliable interlocking operation is possible.

Furthermore, the spacing between the two sets of multiple push button switches can be easily changed by simply changing the lengths of the supports and the connectors, so a desired spacing can be easily obtained.
