Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a push button device for operating a switch or the like.

[0002]

[Prior art]

 Conventionally, as this type of push button device, those shown in FIGS. 13 and 14 are known. In the push button device shown in FIG. 13, a plurality of buttons a are independent from each other, and are attached to the button mounting holes c of the escutcheon b mounted on the front surface of an electronic device or the like from the front surface of the escutcheon b. A light-shielding wall d is formed on the escutcheon b to prevent light from leaking to the adjacent button a side when the button a is illuminated from the back surface.

Further, in the push button device shown in FIG. 14, each push button a is integrated by a connecting portion e, and after the escutcheon b is attached to the button attachment hole c from the back side, a light shielding member formed of sponge or the like is used. Each button a is attached to the escutcheon b by fitting f around each button a and pressing it with a light guide material (not shown).

[0004]

[Problems to be solved by the device]

 However, in the conventional push button device shown in FIG. 13, since the structure of the button a and the escutcheon b is complicated, the cost of the mold for molding them is high, and the button a and the escutcheon b are accurately manufactured. If it is not manufactured, there will be backlash between the two after the button is attached, and the quality will deteriorate.

Further, since the buttons a are independent of each other, a large number of man-hours are required to attach the buttons a to the escutcheons b, and there are problems such as poor assembly.

On the other hand, the push button device shown in FIG. 14 can simplify the structure and assemblability by integrating the buttons a by the connecting portion e, but requires a light shielding member f separately, so that it is a component. As the number of points increased, it was difficult to select the material of the light shielding member f.

The present invention has been made in order to improve the conventional problems, and an object thereof is to provide a push button device having a simple structure and easy to assemble.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention forms a plurality of button members having different button positions, and attaches these button members together to an escutcheon. It is provided with a flange into which the side edge fits.

[0009]

[Action]

 With the above configuration, the work of assembling the button to the escutcheon can be easily performed, and since the light shielding member is not required, the number of parts can be reduced.

[0010]

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings in FIGS. FIG. 1 is a rear view of the escutcheon, FIGS. 2 and 3 are rear views of button members having different button positions, FIG. 4 is a rear view of the state where these button members are incorporated in the escutcheon, and FIGS. Is a plan view of each button member, FIG. 7 is a sectional view taken along line AA of FIG. 4, FIG. 8 is a sectional view taken along line BB of FIG. 4, and FIG. 9 is taken along line CC of FIG. FIG. 10 is a sectional view taken along the line DD of FIG. 1, FIG. 11 is a sectional view taken along the line EE of FIG. 2, and FIG. 12 is a sectional view taken along the line FF of FIG. .

In these figures, the side edge 1b is formed around the front plate 1a at a right angle to the front plate 1a, and the front plate 1a has a convex spherical surface as shown in FIG. A rectangular button mounting hole 1c that is long in the lateral direction is opened. In addition, on the back surface of the front plate 1a, a laterally long projection 1d is provided above the button mounting hole 1c, and a plurality of projections 1e are provided below the projection 1d at intervals. A gap 1f is formed between the protrusion 1e and the protrusion 1d, and the protrusion 1e located above the corner of the button mounting hole 1c is formed in a substantially L shape as shown in FIG.

The buttons 2a and 3a attached to the escutcheon 1 are composed of button members 2 and 3 having different positions of the buttons 2a and 3a as shown in FIGS. 2 and 3.

In the button member 2 shown in FIG. 2, two buttons 2a are provided every other one, and the upper part thereof is continuously connected by an elongated connecting portion 2b in the lateral direction, and at the periphery of each button 2a. Is integrally formed with a flange 2c.

A pressing protrusion 2d for pressing the switch 4 is provided on the back surface of the flange 2c provided on the lower piece of the button 2a, and a front surface of the flange 2c provided on both sides of the button 2a is provided. A recessed groove 2e into which both side edges of a button of a button member 3 to be described later are fitted is formed.

On the other hand, the button member 3 is provided with three buttons 3a every other one, and when combined with the button member 2, the button member 2 is provided between the buttons 3a on both sides and the central button 3a. The respective buttons 2a are positioned, and the upper portions of the respective buttons 3a are connected laterally by an elongated connecting portion 3b.

The connecting portion 3b is adapted to be fitted to the connecting portion 2b of the button member 2 from the front-rear direction as shown in FIG. 7, and the buttons 3a located on the upper and lower sides and both sides of each button 3a. A flange 3c is integrally formed on the outer side of each of the buttons, and a pressing projection 3d of the switch 4 is provided on the back surface of the flange 3c formed on the lower side of each button 3a.

The structure of the escutcheon 1 and the button members 2 and 3 has been described above. Next, the operation of assembling the escutcheon 1 and the button members 2 and 3 will be described with reference to FIGS. 8 and 9.

In FIGS. 8 and 9, 5 is a printed circuit board to which a plurality of switches 4 are attached, and 6 is a light guide member. In assembling, first, the button members 2 and 3 are assembled as shown in FIGS. 4 and 7, and in this state, the connecting portions 2b and 3b are formed between the protrusion 1e formed on the back surface of the escutcheon 1 and the protrusion 1d. Press fit into the gap 1f.

As a result, the buttons 2a, 3a of the button members 2, 3 project from the button mounting hole 1c to the front side of the escutcheon 1 as shown in FIG.

Next, the light guide member 6 is attached to the escutcheon 1 in this state. As shown in FIG. 9, the light guide member 6 abuts the tips of the ridges 1d and the protrusions 1e of the escutcheon 1 to fix the connecting portions 2b and 3b of the button members 2 and 3, respectively. Then, the printed circuit board 5 is attached to the escutcheon 1. The escutcheon assembly thus formed is attached to the front of an electronic device or the like (not shown).

The light guide surface 6a of the light guide member 6 is fitted into the buttons 2a and 3a from the inside, and the buttons 2a and 3a are illuminated from the inside by light guided from a light source (not shown). Pressing projections 2d and 3d provided on the back surfaces of 2a and 3b come into contact with the switch 4.

By this, when each of the buttons 2a and 3a is pressed, the buttons 2a and 3a and the connecting portions 2b and 3b are elastically bent, and the switch 4 can be operated by the pressing protrusions 2d and 3d.

[0023]

[Effect of device]

 As described in detail above, this invention preforms a plurality of button members having different button positions, and combines these button members into the escutcheon, so that each conventional button is independent. Compared with the existing ones, the man-hours required for assembly can be significantly reduced, and the structure of the buttons and escutcheons will be admirable, so the structure of the mold for forming these will be simple, which also reduces the mold cost. Can be planned.

Further, since light is prevented from leaking due to the overlapping of each button at the flange portion, a light-shielding member is not required as in the conventional case, whereby the number of parts and the cost can be reduced.
