Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to an opening/closing device for an adjustment device that houses various adjustment buttons, etc. of a television receiver or the like.

(b) Prior art The adjustment device for equipment such as television receivers is housed inside the equipment or is exposed to the outside of the equipment, as described in Japanese Utility Model Publication No. 62-46376.
There is something like the one shown in , but it has a very complicated structure and has an extremely large number of parts.

(c) Problems that the invention aims to solve This invention was created in view of the above points,
It is an object of the present invention to provide a simple opening/closing device for an adjustment device with a small number of parts.

(d) Means for solving the problem The opening/closing device of the present invention includes an operation button provided on the front of the device, a first locking portion, and a second locking portion provided below the first locking portion. an elastic locking means having an inclined surface provided between the first locking portion and the second locking portion; a front operation portion in which various adjustment buttons of the device are arranged; and a front operation portion near the front operation portion. It consists of a locking piece provided on a side surface and an adjustment device storage means having a pivot portion provided at an end facing the front operating section.

(E) Effect With the above-described structure, the adjustment device housing means is in a state where the entire surface operating section is housed in the device by the locking between the locking piece and the first locking portion, so that the adjustment device storage means can be operated. By pressing the button, the protrusion and the first
The locking part is released and the adjustment device storage means rotates downward about the pivot part due to its own weight,
The front operation section is exposed to the outside of the device, and the rotational descent is stopped by the locking between the locking piece and the second locking means.

(f) Embodiment An embodiment of the switchgear of the present invention will be described below with reference to the drawings.

Fig. 1 is a front view of a television receiver embodying the present invention, Fig. 2 is a perspective view thereof, and Fig. 3 is a drawing for explaining the operation of the opening/closing device of the present invention.
It is a sectional view taken along line AA' in the figure. FIG. 4 is also a drawing for explaining the operation of the opening/closing device of the present invention, and only main parts are shown for easy understanding. In these figures, 1 is a cathode ray tube, 2 is a front frame body, 3 is an operation button, 4 is an elastic locking means,
5 is an adjustment device storage means. Furthermore, 6 is a pressing part provided on the operation button 3, and the elastic locking means 4
The contact piece 7, which will be described later, is in contact with the contact piece 7 provided thereon.
Reference numeral 8 denotes a front operation section provided in the adjustment device storage means 5, and various adjustment buttons (not shown) protrude from holes 9 provided here, and by adjusting these, the brightness, color tone, and image quality of the television receiver can be adjusted ,
Volume etc. are adjusted. Further, reference numeral 10 denotes a locking piece provided on a side surface near the front operation section, and 11 a pivot section provided at an end facing the front operation section, through which the adjustment device storage means 5 is rotated and lowered. It forms the axis of rotation when Reference numeral 12 denotes a claw for preventing the adjusting device storage means 5 from rotating downward beyond the normal rotation range and falling off downward. 13
is provided on the elastic locking means 4, and locks with the locking piece 10 when the front operation section 8 of the adjustment device storage means 5 is stored in the device;
is provided in the elastic locking means 4, and when the front operation section 8 of the adjustment device storage means 5 is exposed to the outside of the device, when it locks with the locking piece 10, the second locking section 1
Reference numeral 5 denotes an inclined surface provided between the first locking part 13 and the second locking part 14, on which the locking piece 10 slides when the adjustment device storage means rotates downward; Reference numeral 7 denotes a contact piece with which the pressing portion 7 of the operation button 3 comes into contact. Next, these operations will be explained. Normally, the adjustment device storage means 5 is in a state where its front operation section 8 is stored in the device, as shown in FIGS. 1 and 3A. In this state, the operator cannot make any adjustments. In this state, as also shown in FIG. It is maintained by being present. The elastic locking means 4 is screwed to the front frame main body 2 as shown in FIG. 3, and the rotating shaft 16 of the pivot 11 is also fixed to the front frame main body 2, although not shown. Here, when the operator wishes to make some adjustment, when the operator presses the operating button 3, the pressing part 6 of the operating button 3 pushes the contact piece 7 against the biasing force of the elastic locking means 4. By compressing, the elastic locking means 4 is bent and the engagement between the first locking portion 13 and the locking piece 10 is released. (See arrows B to E in FIG. 3A and FIG. 4A.) As a result, the adjustment device storage means 5 begins to rotate downward in the direction of arrow F in FIG. 4A. At this time, the locking piece 10 slides down the inclined surface 15 of the elastic locking means 4. When the locking piece 10 engages with the second locking portion 14, the adjustment device storage means 5 stops rotating downward. This state is shown in FIG. 3C and FIG. 4B. In this state, the front operation section 8 of the adjustment device storage means 5 is exposed outside the device, and the operator can make desired adjustments by operating adjustment buttons (not shown). After adjustment, move in the direction of arrow G in Figure 3 C.
By pushing the adjusting device storage means 5 until the first locking part 13 and the locking piece 10 engage with each other, the third
The state shown in Figure A will be reached.

(g) Effects of the invention As described above, in the present invention, since the adjustment device storage means 5 rotates downward and opens and closes due to its own weight, there is no need to provide a special drive means such as a spring. Also, due to the biasing force of the elastic locking means 4 in the front direction of the device,
The first and second locking portions 13, 14 and the locking piece 10 are held engaged and the operation button is biased outward from the device, resulting in a significant reduction in the number of parts.
