Description

[0001]
[Industrial applications]
The present invention relates to a hinge device for an opening / closing lid that opens and closes a small window formed for operating a setting unit (usually, a portion with a small number of operations) in an electronic device.
[0002]
[Prior art]
Conventionally, in electronic devices, various settings are usually performed on the surface of the device. However, when operations other than the normal operation of the device, such as signal calibration and checking, are performed, the operation unit is provided. Without exposing it to the surface of the device, and put a lid on it to prevent accidental operation.
[0003]
For example, as shown in FIG. 6, a small window 4 is formed in an operation panel 3 of a case 2 of the electronic device 1. As shown in FIG. 7, the front surface of the small case 5 is opened, and mounting plates 8 and 9 are integrally connected in a direction perpendicular to the outside on the open side of the side plates 6 and 7, and a central portion of each of the mounting plates 8 and 9 is formed. Are formed with mounting holes 10 and 11. Mounting holes 10 and 11 are formed in the lower portions of the side plates 6 and 7 on the open side. Shaft holes 12 and 13 are formed in lower portions of the open sides of the side plates 6 and 7 so as to face each other. A volume knob 15 is supported on the rear operation surface 14.
[0004]
The opening / closing lid 17 for opening and closing the small window 4 has support plates 18 and 19 integrally connected to the back of lower portions on both sides, and shaft holes 20 and 21 are formed in the support plates 18 and 19 so as to face each other. The support plates 18 and 19 of the opening / closing lid 17 are inserted inside the side plates 6 and 7 of the small case 5, and both sides of the hinge shaft 22 are inserted into the shaft holes 12, 20, 21 and 13 on both sides. E-rings 25 and 26 are engaged with annular grooves 23 and 24 formed on the protrusions on both sides of the hinge shaft 22, and the hinge shaft 22 is prevented from coming off, and the opening / closing lid 17 is turned around the hinge shaft 22. It is movably supported.
[0005]
Then, the mounting plates 8 and 9 are mounted on both sides of the small window 4 inside the operation panel 3 of the case 2 by using bolts and nuts 27 (see FIGS. 2 and 3) by using the mounting holes 10 and 11. 4 is opened and closed by the opening / closing lid 17.
[0006]
Therefore, the volume knob 15 can be operated by rotating the opening / closing lid 17 to open the small window 4.
[0007]
[Problems to be solved by the invention]
However, in the conventional hinge device as described above, the hinge shaft 22 is usually turned and thus expensive, and in addition, grooves 23 and 24 are formed at both ends. Since the shaft 22 is thin, it is easily deformed at the time of processing, which causes difficulty in processing and further increases the cost. The E-shaped rings 25 and 26 are engaged with the grooves 23 and 24 by using a special tool or radio pliers. However, since the hinge shaft 22 is thin and the E-rings 25 and 26 are small, deformation may occur. In addition to the difficulties, there is a problem that the opening / closing lid 17 serving as the product surface may be damaged during assembly.
[0008]
The present invention solves the above-mentioned conventional problems, does not require difficult processing for the hinge shaft, and can easily assemble the open / close lid to prevent damage to the open / close lid. It is an object of the present invention to provide a hinge device for a small window opening / closing lid for an electronic device, which is capable of improving the assembly workability and reducing the cost.
[0009]
[Means for Solving the Problems]
The technical means of the present invention for achieving the above object includes a first and a second shaft hole formed to face both side surfaces of the electronic device on the small window side, and the first and second shaft holes formed on both sides of the opening / closing lid of the small window. First and second shaft holes formed as described above, a hinge shaft having both sides inserted through the small window side and the first and second shaft holes of the opening / closing lid, and a first shaft on the small window side. A bifurcated first retaining member that is provided outside the hole and that allows the hinge shaft to be inserted and that is deformed after insertion to prevent the hinge shaft from being pulled out backward in the insertion direction. And a second retaining member that is provided outside the second shaft hole on the small window side and that prevents the hinge shaft inserted through the second shaft hole from falling forward in the insertion direction. It is provided.
[0010]
In the above technical means, the first and second shaft holes are formed on both side surfaces of the small case attached to the case of the electronic device, and the first and second retaining members are integrally connected to the small case. It is preferable to set up.
[0011]
[Action]
According to the present invention configured as described above, the hinge shaft is inserted from the bifurcated retaining member into the small shaft side and the first shaft hole of the opening / closing lid, and the opening / closing cover and the second shaft hole of the small window side. By deforming the first retaining member in a state where one end of the hinge shaft is retained by the second retaining member, the other end of the hinge shaft is retained by the first retaining member, and the hinge is secured. The opening / closing lid can be supported rotatably about the use shaft. As described above, difficult processing for the hinge shaft is not required, and the opening / closing lid can be easily assembled, so that damage to the opening / closing lid can be prevented.
