Description

[Detailed Description of the Invention] The present invention relates to a push button operating device for electrical equipment such as tape recorders and record players, and its purpose is to provide a push button operating device that has a simple configuration and is easy to assemble.

Generally, when the power switch of a record player is configured to be operated by pressing a push button,
Due to the installation space in the main body of the device, there are times when it is necessary to arrange the push button body in the direction of pressing operation and the direction of push operation in the push switch body in a substantially orthogonal relationship, so the configuration was as shown in Fig. 1. . In FIG. 1, a push switch main body 1 mounted on a printed circuit board 14 is disposed facing a mounting plate 2, and a spring 9 is disposed between the operating shaft 4 and the mounting plate 2, so that the push switch main body 1 is fixed to a printed circuit board 14, and a spring 9 is disposed between the operating shaft 4 and the mounting plate 2. On the other hand, a push button body 5 is attached to the tip of the shaft 3 pivoted so that it can be pressed in the axial direction against the mounting plate 2.
The inclined piece 15 provided integrally with the shaft 3 was configured to abut against the tip of the operating shaft 4 of the push switch main body 1. However, in the push button operation device described above, when the push button body 5 is pressed, the shaft 3 is inserted into the through hole 10 of the mounting plate 2.
At the same time, the protrusion 11 of the push button body 5 is guided by the vertical wall surface 2a of the mounting plate 2 and slides.In order to make the operation of the push button body 1 smooth, the angle of inclination of the inclined piece 15 must be adjusted. It is necessary to make the push button body 5 larger.
The push operation stroke becomes large and the operation feeling is not very good, and the push switch main body 1 cannot be placed far apart, making it unsuitable for remote control. It had the disadvantage of losing it.

Additionally, in order to compensate for this drawback, a device as shown in FIG. 2 was created. That is, in FIG. 2, the push switch main body 1 attached to the printed circuit board 14
is disposed facing the mounting plate 2, and a holder 13 is attached to the tip of the operating shaft 4, and a spring 9 is disposed between the operating shaft 4 and the mounting plate 2 to provide elasticity in one direction. It is energizing. On the other hand, a shaft 3 having a push button main body 5 attached to its tip is pivotally mounted on the mounting plate 2 so as to be substantially orthogonal to the operating shaft 4 of the push switch main body 1. They are connected by a rod 12 whose both ends are pivoted by support pins 6 and 7. Therefore, when the push button body 5 is pressed, the shaft 3 is guided through the through hole 10 provided in the mounting plate 2, and the protrusion 11 of the push button body 5 is pushed against the upright wall surface of the mounting plate 2. 2
a, and as the shaft 3 moves in the vertical direction, the holder 13 is guided by the horizontal wall surface 2b of the mounting plate 2 via the rod 12. By sliding in the horizontal direction, the push switch main body 1 can be pressed.

However, such a structure requires that the rod 12 be supported by the support pins 6 and 7, resulting in poor assembly efficiency.

This invention was made to solve the above-mentioned conventional problems.The rod, shaft, and holder are connected by bendable hinges provided at both ends of the rod, and these are integrally molded from synthetic resin. , which is easy to assemble.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The difference between FIG. 3 and FIG. 2 is that the push button body 5 and the push switch body 1 are connected by a synthetic resin molded product 8. Here, the molded product 8 has the push button body 5 attached to its tip, and the other end is fitted into the through hole 10 of the mounting plate 2, so that it is pivotally mounted to the mounting plate 2 so as to be slidable in the vertical direction. a shaft portion 8a; a holder portion 8b fitted to the tip of the operating shaft 4 provided on the push switch main body 1;
A rod portion 8e is integrally formed with the shaft portion 8a and the holder portion 8b and has thin portions 8c and 8d near the shaft portion 8a and the holder portion 8b, respectively.

In the push button operating device having such a configuration, when the push button main body 5 is pressed, the shaft portion 8
a is guided to the through hole 10 of the mounting plate 2, and the protrusion 11 provided on the push button body 5 is guided to the mounting plate 2.
It slides in the vertical direction guided by the vertical wall surface 2a. As the shaft portion 8a slides in the vertical direction, the holder portion 8b is guided by the horizontal wall surface 2b of the mounting plate 2 via the rod portion 8e and slides in the horizontal direction. At this time, the rod portion 8
e is bent and displaced from thin-walled portions 8c and 8d at both ends thereof, and acts to apply the movement of the shaft portion 8a to the holder portion 8b as movement in a different direction. When the push switch body 1 is pressed against the biasing force of the spring 9, it is locked by a locking mechanism provided on the push switch body 1 itself. In this locked state, the push button body 5 and the push switch body 1 are connected by the molded product 8, so that the height of the push button body 5 is reduced by the vertical stroke of the shaft portion 8a. . On the other hand, when the pushbutton body 5 is pressed again, the locking mechanism provided in the pushbutton body 1 itself is activated and unlocked, and the operating shaft 4 of the pushbutton body 1 is returned to its original position by the biasing force of the spring 9. be pushed back to the state of At this time, the holder portion 8b at the tip of the operating shaft 4 of the push switch body 1 is guided by the horizontal wall surface 2b of the mounting plate 2 and pushed back. As the holder portion 8b returns, the rod portion 8e is bent and displaced from the thin wall portions 8c and 8d, and acts as a pushing force in the vertical direction on the shaft portion 8a, causing the shaft portion 8a to move through the mounting plate 2. While being guided into the hole 10, the protrusion 11 of the push button body 5 is guided into the vertical wall surface 2 of the mounting plate 2.
a, the shaft portion 8a can be pushed back to its original state, and the push button body 5 can be pushed back to its original height.

In the above embodiment, the case where the push switch main body 1 is installed relatively close to the push button main body 5 has been explained, but in addition to this, the case where the push switch main body 1 is installed relatively far away as shown in FIG. A long holder portion 8b can be integrally provided, and the push switch main body 1 can be remotely operated in a direction different from the pressing operation direction of the push button main body 5.

As described above, according to the present invention, the shaft part to which the push button body is attached and the holder part to which the operating shaft of the switch body is attached are integrally connected by a synthetic resin with a rod part having hinge parts at both ends. When the push button body's pressing direction and the switch body's pressing direction are arranged in a substantially perpendicular relationship, the operating stroke of the push button body can be small, and by integrally molding the shaft, rod, and holder, the operation stroke can be relatively short. Requires fewer parts,
It is easy to assemble and highly suitable for mass production. and,
Since the switch body can be placed far away from the push button body, it is suitable for remote control, and has great practical effects.
