Abstract

(57) [Abstract] [Purpose] In a multiple push button device having a plurality of push buttons, a hinge having a connecting function with each button and a fulcrum function of each button are separated so that when the button is operated, other buttons and the like are shared. I made sure that there would be no malfunctions that would move. According to the present invention, a plurality of push buttons 11a and 11b are integrally connected by a hinge 44, and arc-shaped fulcrums a and b are provided on the respective buttons, and the fulcrums a and b are provided on the front surface of the device. Escussion 20 and back plate 5 on the back
The feature is that they are engaged and supported between 0s.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a push button device used in an electronic device or the like.

[0002]

[Prior Art]

 In a multiple pushbutton device having a plurality of pushbuttons, the manufacturing cost and the mounting cost are increased due to an increase in the number of buttons, which means that the structure in which the plurality of pushbuttons are connected by a hinge or the like is adopted. Has been. This hinge has a connection function with each button, a fulcrum function of each button, and the like. That is, the fulcrum of each button is shared by this hinge. 2A and 2B show an example of the related art, in which FIG. 2A is a partial perspective view of a relationship, and FIG. 2B is a sectional view of the relationship. Reference numeral 1a is one push button, and 1b is the other push button, which are integrally connected by a hinge 4. These push buttons are installed by engaging the hinge 4 with a hinge fixing rib 2'of the escutcheon 2 of the device body. In addition, 3 is an opening part, 1a 'and 1b' are press parts with respect to a switch.

[0003]

[Problems to be solved by the device]

 However, as can be seen from FIG. 2, in the prior art, when one push button 1a is pushed, the other push button 1b integrally connected by the hinge 4 (shared the fulcrum portion) also moves together. was there. Further, since the hinge portion is forcibly pressed by a rib or the like, stress is applied to the hinge portion, which is also a cause of cracking.

An object of the present invention is to provide a push button mounting structure in which the above problems are effectively devised.

[0005]

[Means for Solving the Problems]

 A push button characterized in that a plurality of push buttons are integrally connected by a hinge, each push button is provided with an arc-shaped fulcrum portion, and the arc-shaped fulcrum portion is engaged and supported by a support portion on the device body side. It has a mounting structure.

[0006]

[Action]

 In the present invention, since the hinge and the fulcrum portion are separated, even if a plurality of pushbuttons are integrally connected by a hinge, the pushbutton of one pushes the other pushbutton together. Absent. That is, the pushed push button smoothly rotates by its fulcrum portion and the supporting portion on the device main body side, while the other connected push buttons bend the hinge and the fulcrum portion of each button and the supporting portion on the device main body side. Does not work together in relation to holding the department.

[0007]

【Example】

 An embodiment of a push button mounting structure according to the present invention will be described below with reference to the drawings. 2A and 2B show the present invention, in which FIG. 2A is a perspective partial view of the relationship, and FIG. 2B is a cross-sectional view of the relationship. Reference numeral 11a is one push button, and 11b is the other push button, which are integrally connected by a hinge 44. The connecting portion of each push button to the hinge 44 is provided with substantially arcuate fulcrums a and b. The fulcrums a and b are sandwiched and supported between the escutcheon 20 of the device body and the back plate 50 provided on the inner side of the printed circuit board 51. Reference numeral 52 is a space portion, 30 is an opening portion, and 12a and 12b are pressing portions for the switch 53 and the like.

Next, the operation of the present invention will be described. First, when one push button 11a is pushed, the fulcrum portion a supported by the back plate 50 and the escutcheon 20 rotates there, and the switch 53 is operated by moving the pushing portion 12a. At this time, the other push button 11b does not move like the conventional structure. That is, the other push button 11b has its fulcrum portion b supported and fixed by the escutcheon 20 and the back plate 50, and some rotational force transmitted from the hinge 44 may not be absorbed by the bending of the hinge portion. It does not cause synergy. Further, since the hinge 44 is installed in the space 52, it has a freedom of movement and does not require extra stress as in the conventional case. In addition, in the configuration of the above-described embodiment, the configuration can be variously modified without departing from the scope of the present invention.

[0009]

[Effect of the device]

 As is apparent from the above description, the push button mounting structure of the present invention has a structure in which the connection function (hinge) with each button and the fulcrum function are separated and integrally configured. Despite this, there is no joint movement, and no extra stress is applied to the hinge of the connecting part. Also, since the mounting structure is simple, it is possible to improve workability and stabilize the quality of manufacturing.
