DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone button mounting structure.

[0002]

2. Description of the Related Art Conventional key telephones having a plurality of lines of line buttons are usually arranged in series, for example, four buttons, eight buttons.
The buttons are classified by type, such as buttons and 16 buttons. As for the form of the line buttons, four buttons are arranged in one row and four line buttons are arranged, and eight buttons are arranged in two columns and four line buttons are arranged horizontally. In the case of 16 buttons, four line buttons are arranged in four rows and four rows. In this case, the line buttons are individually mounted one by one as many as the number of lines, or are formed as a set of dedicated parts such as dedicated for four buttons, dedicated for eight buttons, dedicated for 16 buttons, etc. In this case, a structure is adopted in which the buttons are separated and assembled when mounted on the operation panel.

[0003]

In the above-described configuration and mounting structure of the line button of the conventional telephone, a dedicated part must be provided for each line, and the parts cannot be shared.
Further, once the line buttons are set on the operation panel surface, a separating operation for making the line buttons independent is indispensable. Therefore, there have been problems such as an increase in die equipment investment, an increase in assembling equipment, an increase in assembling man-hours, and the like.

[0004]

SUMMARY OF THE INVENTION A button mounting structure for a telephone according to the present invention is a button telephone having a plurality of line buttons in which the operation panel surface of the telephone is non-planar and has a non-planar shape with a slope. The frames are integrally formed and connected by deformable elastic hinge portions, and the frames are grouped in rows, and all the rows have the same shape and the non-planar inclination of the non-planar operation panel surface to be mounted. Alternatively, it is configured in a step shape so as to match the curvature.

[0005]

Next, the present invention will be described with reference to the drawings.

FIGS. 1A and 1B show an embodiment of the present invention, in which FIG. 1A is a perspective view, FIG. 1B is a side view including a partial cross section, FIG. 2 shows an operation panel surface, FIG. b) 8 buttons,
(C) is a plan view of a case of 16 buttons, FIG. 3 is an enlarged perspective view of a line button part, FIG. 4 shows one set of line buttons (16 buttons), (a) is a plan view of a frame, FIG. 5B is a side view showing a printed board and a switch corresponding thereto, and FIG.
(A) is a plan view showing the case of 4 buttons, and (b) is a plan view showing the case of 8 buttons.

In this embodiment, the buttons 4c and the frame 4a of the line buttons 4 in a plurality of rows are integrally formed and connected by deformable elastic hinges 4b, and are made of ABS resin. Further, the frames 4a are grouped for each row. By setting the shape so that all the rows have the same shape, in the case of four buttons, the frame 4a is divided into four parts.
2 (a), 5 (a)), and in the case of eight buttons, two buttons are secured by dividing the area between the second and third rows by two (FIG. 2). (B), FIG. 5 (b)), and furthermore, in the case of 16 buttons (FIG. 2 (c), FIG. 4).
That is, the frame 4a for 16 buttons is used as a reference.

In this embodiment, the handset 1 and the main body 2 are provided with an LCD display unit 3, a line button 4, a dial button 5, a function button 6, and the like, like a normal key telephone. The line button 4 has four buttons, eight buttons, and sixteen buttons set from the series configuration. In this embodiment, in particular, since the surface of the operation panel 7 has a curvature,
The frame 4a is configured in a stepped manner so that the appearance is the same and the button operation is the same regardless of which of the first to fourth rows of the four rows of the line buttons 4 are mounted. As a series of the line buttons 4 in the embodiment, the row is common to four buttons, and the button array is such that one row is for four buttons, two rows for eight buttons, and four rows for 16 buttons. Is set. The operation panel 7 to which the line button 4 is mounted may be prepared for each number of the buttons 4c, or the same operation panel 7 may be used to cover the line button hole opened by using the decorative panel 8. The form of the line button 4 is not particularly changed.

[0009] Line button 4, the whole is the frame 4a of, displaceable elastic hinge portion 4b from the frame 4a ₁ extending laterally is coupled one by one to the individual buttons 4c,
Holds button 4c. Line buttons 4 are grouped in exactly the same shape for each column, among the three models that make up the series, 4 buttons, only eight buttons, split stair-shaped step-change part of the frame 4a _2, each extending in the longitudinal By doing so, the necessary number of buttons 4c can be secured.

The stiffness of the elastic hinge portion 4b for connecting and holding the frame 4a and the button 4c may be determined according to the type of switch provided on the printed board 9 disposed below the line button 4. For example, in the case of using a switch with a small stroke such as a tact switch having a low recovery elasticity, it is necessary to consider that the stiffness is sufficiently large and to smoothly move the line button 4 alone. When the stroke can be sufficiently secured and the operation load can be secured as in the case of the contact rubber switch 10 of FIG. 1B, the frame 4a and the line button 4 fall off before the operation panel 7 is mounted. It does not matter if the strength is not enough.
Vertical step amount 4d direction 4a ₂ are substantially consistent with the level difference caused by the curvature of the surface of the operation panel 7, 3 when dividing a frame type, which split the frame 41 of the frame 4a,
It goes without saying that the projection amounts are set to be substantially the same even when 42 and 43 are mounted. Further, the contact rubber switch 10 having a contact mounted between the line button 4 and the printed board 9 has the same form with a step amount 4d corresponding to the step shape of the line button 4.

[0011]

As described above, according to the present invention, the line buttons and the frame are integrally connected to each other by a deformable elastic hinge portion, and furthermore, the lines are grouped by rows and all the rows have the same shape. By dividing the frame into four parts for four buttons and two parts in the case of eight buttons by setting the shape so that In addition, the work of disconnecting the line button after attaching the line button to the operation panel is not required, which has the effect of reducing the capital investment as well as the number of assembly steps.
