Description

[Detailed Description of the Invention] The present invention relates to a retaining device for a sub-casing such as a speaker box that is detachably attached to a main body.

Conventionally, in audio equipment in which the speaker box can be freely separated from the main body, hinges, hooks, etc. have been used to connect the two, but these have the drawbacks of poor operability for attachment and detachment and poor appearance.

The present invention was devised in view of the above-mentioned drawbacks, and an object of the present invention is to provide an inexpensive and reliable retaining device that is easy to attach and detach.

The present invention will be explained in detail below with reference to embodiments shown in the drawings.

Figure 1 is an exploded perspective view of the present invention applied to a cassette tape recorder with a radio receiver, in which a pair of speaker boxes (sub-casings) 2, 2 are removably attached to both sides of the main body 1. .

Four joint shafts 4 and one engagement recess 6 are provided on both sides of the main body 1, respectively.

On the other hand, the sub-casing 2 is provided with a joint hole 3 at a position corresponding to the joint shaft 4, and the engagement recess 6
An elastic engagement piece 5 is provided at a position corresponding to , with its engagement portion 7 protruding outward.

Here, the head of the joint shaft 4 on the side of the speaker box 2 is a head 4a having a larger diameter than the shaft, and the joint hole 3 corresponding to this is a large hole 3 having a larger diameter than the head 4a.
a and a small hole 3 having a smaller diameter than the head 4a and a larger diameter than the shaft 4.
b is made up of continuous holes.

In the drawings, the elastic retaining piece 5 is attached to the speaker box 2 as a separate piece, but it may be formed integrally with the box 2.

To attach the speaker box 2 to the main body 1, first align the heads 4a of the four joint shafts 4 of the main body 1 with the large holes 3a of the four joint holes 3 of the speaker box 2 as shown in FIG. After inserting the speaker box 2 in the direction C, slide the speaker box 2 into the head 4a as shown in FIG.
are made to face the small hole portion 3b and the two are combined.

At this time, the elastic retaining piece 5 is bent in the direction A, and eventually its engaging portion 7 engages with the engaging recess 6 of the main body 1, so that the speaker box 2 is prevented from coming off.

Also, when separating the speaker box 2 from the main body 1, push the operating portion 8 of the elastic engagement piece 5 in the direction A to separate the speaker box 2 from the main body 1.
By sliding in direction B, the main body 1 and the speaker box 2 can be separated.

As described above, the present invention has an extremely simple structure that allows the main body and sub-casing to be attached and detached, and is also securely prevented from coming off, making it convenient for practical use.
