Description

[Detailed description of the invention] This invention relates to a push button actuating device for operating a switch in an electrical device. The object of the present invention is to provide a pushbutton actuation device that allows the switch to be operated reliably in any direction perpendicular to its axis.

Figure 1 shows a push button b using a conventional spring a.
This is the actuating device for switch c, but with this kind of structure, if push button b is made larger (increased diameter), the center part will work better, but if you press it anywhere other than the center part, the operation will be uncertain and the switch will not work properly. It was impossible to operate except by pressing in the axial direction.

Furthermore, FIG. 2 shows another example of the conventional push button b, in which a hinge part d is provided at one end of the push button b, and this hinge part d has the function of a rotating shaft.
Although stable operation can be obtained, push button b cannot be pushed in a direction perpendicular to the axial direction of switch c.

In Figs. 1 and 2 above, e is a protrusion formed on the back of push button b, which is brought into contact with switch c to operate the switch by pushing push button b. , and f is an operation panel that holds the push button b from the outer periphery and exposes it to the front.

This invention enables pushbutton operations that cannot be achieved with the conventional pushbutton actuation devices described above, that is, a large pushbutton that allows the switch to be operated in either the direction of the switch's operating axis or in the direction perpendicular to the operating axis. The present invention provides a push button actuating device that can reliably operate a push button even when the push button is pressed.

FIG. 3 is an external view of the push button part of an electrical device using this push button actuating device. It can also be pressed from any direction. In addition, 2
2 is the front operation panel of the electrical equipment, and 2' is the top operation panel.

Figure 4 shows a side sectional view of Figure 3, where 3 is a switch installed in the electrical equipment, 4 is a switch installed in the electrical equipment;
is an L-shaped member formed of synthetic resin into a substantially L-shape, with its bent portion serving as a hinge portion 5, one piece serving as a fixed portion 6, and the other portion serving as a movable portion 7;
8 is a protrusion provided on the back of the movable part 7 of this L-shaped member 4, which is brought into contact with the switch 3;
This causes the switch 3 to be pushed.

This L-shaped member 4 has its fixing portion 6 fixed to the inside of the top operation panel 2' as shown, and
A relatively large push button 1 is attached to the front surface of a movable part 7.

With the push button actuating device configured in this way, when the push button 1 is pressed in the direction of arrow A, that is, in almost the same direction as the operating axis direction of the switch 3, the L-shaped member will move as shown in FIG. 4 movable part 7
The switch 3 rotates about the hinge portion 5 as a fulcrum in the direction of arrow C in the figure, so that the switch 3 can be pressed by the protrusion 8 and activated.

In this case, even if the front surface of the push button 1, that is, the surface in the direction of the arrow A, is wide, the structure of the L-shaped member 4 makes it possible to smoothly press the push button 1 at any position in the direction of the arrow A. This is advantageous compared to the conventional method in which the push button must be pressed at a position substantially coincident with the operating axis direction of the switch 3.

The push button 1 can also be operated in the same manner as shown in FIG. 5 by pressing it in a direction substantially perpendicular to the operating axis of the switch 3, that is, in the direction of arrow B in the figure. can be done. In this case, by making the surface of the push button 1 in the direction of arrow B as wide as possible and increasing the distance from the hinge portion 5, smoother operation can be achieved.

Furthermore, by lengthening the movable portion 7 of the L-shaped member 4, the distance from the hinge portion 5 is increased, thereby allowing smooth operation even when using a large push button 1.

In the push button actuating device of this invention, as described above,
It has an L-shaped member made of synthetic resin, with one piece serving as a fixed part and the other piece serving as a movable part, and these parts are connected at a substantially right angle, and a hinge part is formed at the connecting part,
The fixed part is fixed to the inside of the operation panel, a push button with a large width in the extending direction of the movable part is attached to the front of the movable part, and a protrusion for pushing the switch is attached to the back of the movable part. Although the structure is relatively simple, the switch can be operated reliably in either direction of the switch's operating axis or in a direction approximately perpendicular to the operating axis. It has features such as being able to
