Description

[Detailed description of the invention] This invention relates to a lid mounting device, and more specifically, a lid mounting device for opening and closing a lid that covers specific knobs on the operation panel of a television receiver, etc. It is related to the device.

When it comes to television receivers, the operation panel has many frequently used operation knobs such as the power switch, channel selection switch, and volume adjustment knob, as well as brightness adjustment knobs, hue adjustment knobs, etc. There are control knobs and the like that you don't have to touch much once you're done. Leaving all of these operating knobs exposed on the operating panel surface not only leads to erroneous operations but is also undesirable in terms of design. Therefore, knobs that do not need to be touched often are covered with a lid, but in this case, conventionally, the lid is attached to the operation panel via a hinge or similar metal fittings. Therefore, it is not suitable for mass production because it has a large number of parts and requires extra assembly man-hours.

This invention was made in view of the above-mentioned circumstances, and its purpose is to provide a lid attachment device that has a simple structure and can quickly attach the lid with a one-touch operation without using any special tools. There is a particular thing.

Hereinafter, this invention will be described in detail with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows an embodiment in which a lid 2 is attached to an operation panel 1 of a television receiver. The operation panel 1 has a lid mounting surface 3 which is generally formed low so that the lid 2 can be mounted thereon.The lid mounting surface 3 has, for example, a plurality of push button type channel selection switches 4 and a window 7 for mounting a power switch. In addition, there are provided a window 5 for mounting knobs that are not often used, such as a brightness adjustment knob and a hue adjustment knob, and a window 6 for mounting a light-receiving element for remote control. On the other hand, the lid 2 is formed with a plurality of through holes 8 drilled corresponding to the channel selection switch 4 and large through holes 9 bored corresponding to the mounting windows 6 and 7. A window 5 for attaching knobs, which is not often used, is covered by a lid 2. Note that this lid 2 has four side walls 2a~
It consists of a rectangular box-shaped body with a shallow bottom having a diameter of 2d,
A pawl 11 that elastically engages with a locking hole 10 formed on the operation panel 1 side is connected to the side wall 2b on the rotation end side.

This lid attachment device includes two sets of hinge portions each having a fitting structure of a pair of male and female members arranged on the virtual axis of rotation of the lid 2 with respect to the operation panel 1 described above. Each of the hinge parts is provided on the upper side and the lower side of the lid 2 in FIG. and a female member consisting of a hole 16. In this case, boss 15
is provided on an arm 17 formed to protrude to the side of the lid mounting surface 3 of the operation panel 1, and a bearing hole 16 is bored on the upper side wall 2a side of the lid 2. In addition, the boss 15 is provided on the lid 2 side.
and a stopper piece 1 that maintains the fitted state of the bearing hole 16.
8 is provided. In this embodiment, the stopper piece 18 consists of an elastically deformable tongue piece that is integrally molded on the side wall 2d of the lid 2 on the rotating proximal end side. A locking surface 18a is provided which protrudes and is preferably formed to face the bearing hole 16. Note that the facing distance S between the lower opening surface of the bearing hole 16 and the locking surface 18a is set to be slightly wider than the plate thickness t of the arm 17.

On the other hand, the other hinge part provided on the lower side of the lid 2 is connected to a cylindrical boss 20 as a male member provided on the operation panel 1 side and a lower side wall 2 of the lid 2.
It consists of a bearing hole 21 as a female member bored in c.

In the above configuration, in order to attach the lid 2 to the operation panel 1, first, the bearing hole 2 in the lower hinge part
1 is slightly hooked on the boss 20, and the upper arm 17 is brought into contact with the protruding end of the stopper piece 18. Then, force is applied to the operation panel 1 or the lid 2 to forcibly deform the stopper piece 18 toward the outside of the lid 2 via the arm 17, so that the boss 15 and the bearing hole 16 are fitted together. Due to this fitting, the lid 2 slides downward by the height of the boss 15, so that the bearing hole 21 and the boss 2
0 are completely fitted, and the stopper piece 18
escapes from the arm 17 and returns to its original state, and its locking surface 18a engages with the lower surface of the arm 17. Therefore, the arm 17 comes to be sandwiched between the upper side wall 2a of the lid 2 and the stopper piece 18, and the arm 17
There is no risk of it coming off inadvertently. On the other hand, lid 2
To remove it, deform the stopper piece 18 outward from the lid 2 to release its locking surface 18a from the lower surface of the arm 17, and lift the lid 2 slightly to align each bearing hole 16, 21 with the boss 15. , 20.

Note that, unlike the above embodiment, as shown in FIGS. 2 and 3, the bosses 15 and 20 may be provided on the lid 2 side and the bearing holes 16 and 21 may be provided on the operation panel 1 side. It is possible. Further, the stopper piece 18 may be formed on the front wall 2e of the lid 2. Furthermore, the bearing holes 16 and 21 may be through holes or may be so-called blind holes.

As is clear from the description of the embodiments described above, this invention provides a lid attachment device that has a simple structure that can be integrally formed with the lid and the operation panel, and that can be attached with a single touch operation. This is extremely useful in increasing mass production and reducing costs.
