Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a push button device that attaches a pressing part to a cabinet by attaching a mounting plate connected to the pressing part via a hinge to the back side of the cabinet. .

(b) Prior Art Push button devices of the type in which a pressing portion and a mounting plate are connected via a hinge are shown in, for example, Japanese Utility Model Application No. 123837/1983 and No. 616/1989.

By the way, in the above-mentioned known example, the pressing part (push button part, operation part) is provided continuously. However, there is also a type of push button device in which the pressing parts are spaced apart and a fixing part (escutcheon, decorative plate) is provided between the pressing parts. An example of a push button device including this fixing portion is shown in FIG.

Figure 4 is a view from the back of the cabinet.
10, 10 are fixed parts. 12 is a cabinet, and this cabinet 12 is provided with an opening 14. 16 and 18 are cabinet 12
This is a boss provided on the back surface 12a of the. 20 is a mounting plate, and 22 is a hinge 2 on this mounting plate 20.
4 and 24. 1
0 and 10 are fixed parts connected to the mounting plate 20 via hinges 26 and 26. 28, 28 are holes provided at one end 10a, 10a of the fixed parts 10, 10, and bosses 18, 1 are provided in these holes 28, 28.
8 is inserted. Further, 30 is a hole provided in the mounting plate 20 and through which the boss 16 is inserted.

Mounting plate 20 hinges 24, 24, 26, 26
The pressing portion 22 fixing portions 10, 10 are integrally molded from resin. Then, the mounting plate 20 is attached to the back surface 12a of the cabinet 12 as shown in FIG. At this time, the fixing parts 10, 10 and the pressing part 22 are exposed outside the opening 14. Thereafter, the bosses 16, 18, 18 are melted in the direction of arrow A in the figure, and the mounting plate 20 and the fixing parts 10, 10 are fixed.
Further, in the pressing part 22, the hinges 24, 24 are bent and rotated by a pressing operation by the operator, and press a switch part (not shown).

Incidentally, a side sectional view of the fixing parts 10, 10 is shown in FIG. These fixing parts 10, 10 naturally have nothing to do with the switch operation, but they are provided in close proximity to the pressing part 22, and like the pressing part 22, there is a risk that they may be erroneously subjected to force in the direction of B in FIG. There is.

(c) Problems to be solved by the invention There was a risk that this force would damage the melted portion of the boss 18 that fixes the fixing parts 10, 10.

(d) Means for solving the problem The present invention is connected to a pressing part through a hinge, and is also connected to a fixed part disposed parallel to the pressing part through another hinge. an opening provided in the cabinet for exposing the pressing part and the fixing part to the surface side of the cabinet;
A fusion boss provided on the back surface of the cabinet for fixing the mounting plate to the cabinet, and a fusion boss provided on the back surface and one end of the fixing part to engage both to prevent rotation of the fixing part. In the push button device, the engaging means includes an abutting piece provided at the one end of the fixing portion and abutting the back surface, and a contact piece provided around the opening on the back surface and abutting the one end. The protruding piece that comes into contact with the back side,
This is a push button device.

(e) Effect Since the present invention has the above-described configuration, even if the fixed part is pressed toward the back surface of the cabinet, one end of this fixed part comes into contact with the protrusion and is prevented from moving. Furthermore, even if the fixed portion receives a force directed toward the surface of the cabinet, the abutment piece abuts against the back surface of the cabinet to prevent movement. Further, since the mounting plate is fixed by the fusion boss, after the engaging means is engaged, the fusion boss is inserted into the hole of the mounting plate and attached to the back surface of the cabinet.

(f) Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 to 3. Note that the same parts as in FIGS. 4 and 5 are given the same reference numerals, and redundant explanations are omitted.

Reference numerals 40 and 40 designate protrusions integrally provided on the cabinet 12. These projecting pieces 40, 40 are in contact with the surfaces 42, 42 of the fixing parts 10, 10, and as shown in FIG.
This prevents movement of the fixing part 10 in the direction. Also, 44,
44, 44, 44 are fixed parts 10, one end 10 of 10
This is an abutting piece provided on a and 10a. These contact pieces 44, 44, 44, 44 are in contact with the back surface of the cabinet 12, and the fixed parts 10, 1 in the direction E in FIG.
Prevent movement of 0. Note that the projecting pieces 40, 40 and the contact pieces 44, 44, 44, 44 are connected to the fixed parts 10, 1
One end 10a, 10a of 0 is connected to the back surface 12 of the cabinet.
It forms an engaging means that engages and fixes to a.

As shown in FIG.
The fixing parts 10, 10, etc. are first attached to the opening 14 from the direction of arrow C. At this time, the protrusion 40,4
0 and the contact pieces 44, 44, 44, 44 are respectively on the surface 4.
2, 42 comes into contact with the back surface 12a. Therefore, the one ends 10a, 10a of the fixing parts 10, 10 are as shown in FIG.
It is fixed in the E direction.

The contact pieces 44, 44, 44, 44 are located on both sides of the projecting pieces 40, 40, and also prevent movement in the direction F in FIG. 2. Then, the boss 16 is inserted into the hole 30 of the mounting plate 20 as shown in FIG. 2, and then fused.
In addition, the protruding pieces 40, 40 abutting pieces 44, 44, 4
4, 44, the boss 16 on the back of the cabinet comes into contact with the mounting plate 20 and becomes a hindrance to the installation.
6 and 26 permit engagement of the flexural engagement means.

(f) Effects of the invention As described above, according to the present invention, even if the fixing part and the pressing part are integrally molded, the fixing part can be firmly fixed. Furthermore, the engagement of the engagement means is permitted by the bending of the hinge.
