Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a seesaw type push button device used, for example, in an operating section of a television receiver or the like.

<Summary of the invention> The present invention relates to a seesaw type push button device, and in particular, two shaft supports are provided on a bearing of a cabinet that pivotally supports a seesaw button, and the seesaw button is movable with respect to the two shaft supports. Regarding the installed seesaw type push button device.

<Prior Art> Conventionally, the seesaw type push button device described above has been mainly used to press a two-way selection switch such as a volume adjustment switch or a channel selection switch to increase or decrease the volume or to increase or decrease the channel. There are many. An example is shown in FIGS. 5 and 6.

The seesaw button 1 has a pair of engaging claws 1a, 1a that engage with the opening edge of the cabinet 2, and a pair of operating rods 1b, 1 that press and operate the tact switches 3, 3.
b is provided, and springs 4, 4 are fitted into the operating rods 1b, 1b, respectively, so as to operate the seesaw button 1.
is biased outward. On the other hand, the two tactile switches 3, 3 are mounted on the board 5 and arranged at predetermined positions on the back side of the cabinet 2.

The seesaw type push button device configured in this way is
By pressing the surface end of the seesaw button 1, any tact switch 3, 3 can be operated.

<Problems that the invention aims to solve> However, in recent electronic devices such as television receivers, most of their functions can be controlled remotely using remote control transmitters, which are located on the device itself. The frequency of use of the various operation buttons has decreased significantly. Therefore, it is not preferable to provide a plurality of such operation buttons in terms of component mounting, but in the conventional seesaw push button device described above, only two switches can be operated with one seesaw button. .

<Means for Solving the Problems> In order to solve the above-mentioned conventional problems, in the present invention, the seesaw button is provided with a support arm having a support shaft projection at the tip, and the cabinet is provided with a support arm having a support shaft projection at the tip. Further, the bearing was provided with two shaft supports, and the seesaw button was movably attached to the two shaft supports.

<Function> That is, if the seesaw button is installed as described above and switches are operated at each position, four switches can be operated with one seesaw button.

<Examples> Examples of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 4, 6 is a seesaw button, which has a long plate shape and has a pair of operating rods 6a, 6a and a pair of support arms 6b, 6b on the back side.
Support shaft protrusions 6c, 6c are provided at the tips of b, 6b. Reference numeral 7 designates a cabinet, in which recesses 8 having a concave cross section are formed at predetermined locations. The recess 8
The supporting arms 6b, 6b of the seesaw button 6 are provided on the bottom surface.
Elongated holes 8a, 8a into which the seesaw button 6 is loosely fitted are formed, and bearings 8b, 8b for pivotally supporting the support shaft protrusions 6c, 6c of the seesaw button 6 are formed on the side surfaces. Bearing 8
b, 8b are bored in the shape of elongated holes and have protrusions at their upper edges, forming two shaft supports 8c, 8c', and furthermore, the upper edges have slits bored in their vicinity. 8
It has elasticity due to d and 8d.

The seesaw button 6 has springs 9, 9 inserted into the operating rods 6a, 6a, respectively, and the operating rods 6a, 6a.
6a is loosely fitted into the elongated holes 8a, 8a, and at the same time, the support shaft projections 6c, 6c are fitted into the bearings 8b, 8b. In this state, the spindle protrusions 6c, 6
c is pivotally supported by one of the shaft supports 8c and 8c', but since the upper ends of the bearings 8b and 8b have elasticity, it can be slid to the other shaft support 8c or 8c'. .

Therefore, if the board 11 on which two sets of two tact switches 10a, 10b and 10C, 10d mounted in close proximity are placed on the back side of the cabinet 7 in correspondence with the seesaw button 6, this seesaw button 6, four tact switches 10a, 10b, 1
0c and 10d can be operated.

<Effects of the invention> As described above, according to the seesaw push button device of the invention, four switches can be operated with one seesaw button, so the space occupied by the operating section can be reduced. The miniaturization of equipment can be promoted.

Due to the reduction in the number of parts, installation workability is improved and costs can be reduced at the same time.

The above effects can be obtained.
