Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control transmitter used in a television receiver or the like, and particularly to an improvement in its case.

Fig. 1 shows the external appearance of this type of case, and 1 and 2 are placed in contact with each other to form a box (this box houses the circuits, etc. that make up the remote control transmitter). They are first and second lids, and 3 is a third lid for fixing the first and second lids 1 and 2 facing each other.

As shown in Fig. 2, the case of a conventional remote control transmitter has screws 6 screwed into bosses 4 and 5 formed on the inner surfaces of the first and second lids 1 and 2 on the left side of the case. fixed,
On the right side, the protrusions 7, 7 provided on the inner surface of the third lid body 3 are connected to the first,
The structure was such that the tongues 8, 8 of the second lids 1, 2 were fitted with non-transparent holes 9, 9, which were fixed. However, with this structure, it was difficult to dismantle the case when replacing internal parts. It has been difficult to achieve both workability and fixation reliability.

That is, when replacing electrical parts housed inside the case or repairing or inspecting circuits, it is necessary to remove the screws 6 and forcefully remove the protrusions 7, 7 from the opaque parts 9, 9 on the right side of the case. If the engagement between the protrusions 7, 7 and the opaque 9.9 is configured to be shallow in advance in consideration of such a case, the problem arises that the third lid body 3 is likely to come off due to an external impact.

In particular, since the remote control transmitter is held and operated in the hand, it is often accidentally removed from the hand, dropped, and subjected to impact, so there is a good chance that the third lid 3 will come off.

Therefore, detachment of the third lid body is undesirable because it may cause damage or failure of internal parts.

However, in order to prevent such detachment from occurring, the protrusion 7
, 7 and the opaque parts 9, 9 are deep, it becomes difficult to disassemble the case.

In this way, conventional remote control transmitter cases are not only unable to satisfactorily balance both the workability of disassembling the case and the reliability of the normal fixed state, but also the difficulty of disassembling and reassembling during repairs as mentioned above. It is said that the corners of the opaque parts 9, 9 are worn out due to repeated detachment or assembly due to dropping, and the protrusions 7, 7 become smaller or chipped due to wear, making it impossible to fix them with the third lid body 3. There is a risk that this is not appropriate.

The present invention proposes a new and useful remote control transmitter case that does not suffer from the above-mentioned drawbacks.

The present invention will be described in detail below according to embodiments shown in the drawings.

FIG. 3 shows an exploded view of the case of the present invention, 11 is a first lid, 12 is a second lid, 13 is a third lid, and the side of the first lid 11 has a protrusion 14. is formed in this protrusion 14, and engagement holes 15, 15 and vertical slits 16.
16 are provided.

An insertion portion 17.17 is formed on the second lid 12 in correspondence with the protrusion 14 of the first lid 11.

As clearly shown in FIG. 4, the inner surface of the third lid body 13 has first ribs 18, 18 for engaging with the engaging holes 15, 15.
and the second rib 19,1 that enters the slit 16°16.
9 and third ribs 21, 21 that are supported and abutted on the notch 20 of the second lid 12.

In order to assemble each of these lids as a case, first
The third lid 1 is inserted into the engagement holes 15, 15 of the protrusion 14 of the lid 11.
When the first rib 18.18 of 3 is inserted from above, the second ribs 19, 19 are simultaneously inserted into the slit 16.16, and the first lid 11 and the third lid 13 are fixed in the left-right direction. .

Then, the insertion part 17.17 of the second lid 12 is inserted into the remaining part of the third lid 13 in which the protrusion 14 of the first lid 11 is housed, and the bottom surface of the insertion part 17.17 is inserted into the third lid 13. 5 and 6, the upper ends 17a, 17a of this insertion portion 17.17 are brought into contact with the bottom inner surface 22 of the third lid body 13.
is brought into contact with the bottom surface of the protrusion 14.

At this time, the insertion portion 17 is connected to the protrusion 14 of the lid 11 located above and the bottom inner surface 22 of the third lid 13 located below.
It may be designed so that it comes into pressure contact with the

Although FIG. 3 does not show that the bosses fixed with screws are provided inside the first and second lids 11 and 12 on the left side, the left side portions are similar to the conventional example shown in FIG. It is best to fix it with bosses 4, 5 and screw 6.

According to the present invention, the fixed part on the right side of the case combines the first lid body and the third lid body through the engagement hole, the first rib, the slit, and the second rib, and then connects the second lid body to the first lid body. It has a simple structure that can be inserted between the third lid body and the third lid body, and the ribs are not forcibly removed from the retaining hole and the slit during disassembly, so the disassembly work is easy. Since the engagement between the ribs and the engagement holes and slits can be made deep, the fixed state is firm and the third lid body does not come off due to external impact.
