Abstract

PURPOSE: To simplify a device constitution by providing a seesaw swivel support point, elastic member for parallelly restoring a push button and a swivel support shaft of concurrently playing a role of receiving pushing pressure, integrally formed with the push button and a main unit frame. CONSTITUTION: A push button 2 and a main unit frame 4 of external shape larger than the push button 2 are connected to be integrally formed by a pair of swivel support shafts 1 on one shaft connected to the main unit frame from almost central part of the push button 2, and in the swivel support shaft 1, thickness in a pressing force operating direction against the push button is formed larger than thickness in a direction orthogonal relating to the pushing pressure operating direction. Even when applied a pressure to a pressing part 2c in the vicinity of the swivel support shaft 1, it is not deformed, and when applied pushing pressure to pressing parts 2a, 2b in the vicinity of both ends of the push button, the swivel support shaft 1 is twisted and seesaw swiveled with the push button 2 serving as a swivel support point, to actuate switches 10a, 10b through switch operating bosses 8a, 8b. When a pressing operation is released, the push button is reset to the initial position by twist restoring force of the swivel support shaft.

圧力を受け止めている。The above-mentioned conventional example will be described below with reference to the drawings. FIG. 2A is a perspective view showing the configuration of the essential part of the former conventional seesaw swing type push button. Figure 2
In (a), the push button 12 is integrally formed with the body frame 14 by being connected to the two elastic pieces 3a and 3b. Push button 2
A seesaw swing fulcrum rib 5 is provided in the lower center part of the. When the push button 12 presses the pressing surface 12a at one end apart from the swing fulcrum rib 5, the elastic pieces 3a and 3b are respectively deformed, and the lower end 5a of the seesaw swing fulcrum rib 5 of the push button 12 is provided at the lower portion thereof. The contact point 7 comes into contact with the contact surface 7 and the contact points of both contact the contact surface 7 and the seesaw swings. Push button 1
When the pressing operation on the pressing surface 12a at one end of 2 is released, the push button 12 returns to the original position by the restoring force of the elastic pieces 3a and 3b. The same applies to the pressing surface 12b at the other end of the push button 12. Since the elastic pieces 3a and 3b need to be deformed in the pressing operation direction and the opposite direction, respectively, it is necessary to reduce the wall thickness in the pressing operation direction. In this case, there is no strength against the pressing in the pressing operation direction, and the pressing force must be received by other parts. Therefore, in this case, the pressing force is received by the lower end 5a of the seesaw swing fulcrum rib 5 and the contact surface 7.

The elastic pieces 13a and 13b, which are twisted according to the pressing force applied to the pressing portions 22a and 22b, are formed thin in the pressing direction to facilitate the swinging of the push button 2.
The difference from FIG. 2A is that a seesaw swing support shaft 6 is provided as a separate seesaw swing support point. In this case, the pressing force applied to the pressing surfaces 22a and 22b is received by the seesaw swing support shaft 6.

As shown in (b), there is a problem that a separate seesaw swing support shaft is required, the number of parts is increased, and the number of mounting steps is increased, resulting in an increase in cost. SUMMARY OF THE INVENTION The present invention is intended to improve the above-mentioned conventional problems, and an object thereof is to simplify a seesaw-type push button by using only integrally formed parts.

Of the push button, a body frame that is larger than the outer shape of the push button, and a pair of uniaxial swing support shafts that are connected to the body frame from a substantially central portion of the push button. The body frame is formed integrally with the swing frame, and the swing support shaft is formed such that the thickness in the pressing operation direction with respect to the push button is thicker than the thickness in the direction orthogonal to the pressing operation direction.

Even if a pressing force in the pressing operation direction is applied to the vicinity of the section, the swing support shaft does not deform, and the swing support shaft can be twisted by reducing the thickness in the direction orthogonal to the pressing operation direction. During normal seesaw push button operation, when the pushing parts near both ends of the push button are operated and a pressing force is applied, the swing support shaft is twisted, and the swing support shaft is used as the seesaw swing support point of the push button. When the pressing operation is released, the push button acts so as to return to the initial position by the restoring force of the twist of the swing support shaft.

The push button 2 swings clockwise with the swing support shaft 1 as a fulcrum of seesaw swing. Then, the switch operating boss 8a provided on the push button 2 causes the switch 10a arranged on the printed board 9
Is pressed. At this time, a rotational moment acts on the swing support shaft 1 and is twisted. When the pushing surface 2a of the push button 2 is stopped, the push button 2 returns to the initial position by the restoring force of the twist of the swing support shaft 1, and the push operation of the switch 10a is released. When the pressing surface 2b of the push button 2 is pressed, the swinging direction is reversed but the operation is the same. When the center 2c of the push button 2 is pressed, the swing support shaft 1 is thick in the pressing direction and is not deformed, so that the push button 2 maintains its initial posture. Therefore, the two switches 10a and 10b are not pressed at the same time. Although not shown in the above, the body frame 4 may be optionally provided with a mounting portion or the like for mounting on the chassis or housing of the device.

簡単にすることができる。As described above, in this embodiment, the push button, the swing support shaft, and the body frame are integrally formed, and the swing support shaft has a thickness in the pressing operation direction with respect to the push button with respect to the pressing operation direction. By making the thickness thicker than the thickness in the orthogonal direction, the structure can be simplified without separately providing a member for receiving the pressing operation force.

Even in the case of a shape, the object of the present invention is satisfied if the major axis thereof substantially matches the pressing direction. Further, the pressing force applied to the switches 10a and 10b may be directly transmitted on the back surface of the push button 2 without using the illustrated switch operation bosses 8a and 8b.

効果の高いものである。As described above, the seesaw switch device of the present invention has two pressing points, and a push button for applying a pressing force to each switch below the pressing points, and a push button The main body frame is larger than the outer shape, and a pair of oscillating support shafts on one axis are connected to the main body frame from approximately the center of the push button.The push button, the oscillating support shaft, and the main body frame are integrally formed and Since the drive shaft is formed so that the wall thickness in the pressing operation direction with respect to the push button is thicker than the wall thickness in the direction orthogonal to the pressing operation direction, it can be rocked even if a pressing force is applied near the rocking support shaft. The spindle does not deform, and during normal seesaw pushbutton operation, when the pressing parts near both ends of the pushbutton are operated and a pressing force is applied, the swing spindle is twisted, causing the swing spindle to shake the seesaw shake of the pushbutton. The seesaw can be swung as a fulcrum, and when the pressing operation is released, the oscillating shaft is twisted. By push button is to return to the original position by the restoring force, labor of less then assemble parts requires also less also those highly effective while constraints less simple construction of the button arrangement.
