Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a locking device that allows an in-vehicle audio device to be inserted into and removed from an inner case and that can also change a pause switch.

(Technical Background) In-vehicle audio equipment, such as car stereos and CD players, has become increasingly high-quality and sophisticated in recent years, and as a result, the audio equipment itself is increasingly being stolen. In order to protect the audio equipment from theft, it is necessary to make the audio equipment removable from the inner case attached to the dart board, and to have a mechanism that allows the audio equipment to be easily removed from the inner case when leaving the car. ing.
However, since the main body of the audio equipment is frequently removed and reinstalled, care must be taken to ensure that the dash board itself has sufficient strength and not to damage the internal mechanism of the audio equipment.

(Objectives of the invention and means for achieving the objects) As described above, the present invention protects the main body of the audio equipment directly and efficiently from theft by easily attaching and removing it from the inner case without damaging the internal mechanism of the main body of the audio equipment. It is something.

For this reason, a handle is provided on the front operation section of the audio equipment, and by raising and lowering the handle, the tip of the locking plate of the handle can be inserted into and removed from the locking hole of the inner case, and the locking plate can be inserted into and removed from the locking hole of the inner case. A pose switch can be freely switched using the provided cam side.

(Example) The locking device of the present invention will be explained in detail below based on the drawings.

FIG. 1 is a partially omitted perspective view showing a state in which a main body 2 of an audio device is inserted into an inner case 1. As shown in FIG.

The inner case 1 is formed of a thin steel plate or the like into a box shape with a front opening.
A pair of locking holes 13 and 1 are provided at the corners formed by holes 2 and 12, respectively.
3 is provided.

On the other hand, the device body 2 is a cassette tape player or
It has a built-in CD player, etc., and has a nose, or so-called operating section 21, on the front of its casing, into which a cassette tape or compact disc is inserted. Also, a pause switch is provided on either side 22 through the opening 22a.
SW switching lever L-1 protrudes.

The operating portion 21 is provided with a handle 3 having a substantially square shape formed by a pair of arms 31, 31 and a handle 32. As shown in the schematic side view of FIG. 2, the arms 31, 31 have their tips supported by support shafts P ₁ , P ₁ . Therefore, the handle 32 has a supporting shaft P ₁ ,
Vertical movement centered on _P1 , so-called raising and lowering operations, is possible. On the other hand, locking plates 23 _and 2 are connected via pivots P ₂ and P ₂ toward the handle 32 with respect to the support shafts P 1 and P ₁ .
3 is pivoted. The locking plates 23, 23 have sharp tips 23a, 23a, and semi-arc shaped slide grooves 23b, 23b are formed approximately in the center, respectively. Furthermore, guide pins 24, 24, which are respectively erected on the side parts 22, 22 of the device main body 2, are loosely fitted into the slide grooves 23b, 23b.

Also, a cam side 23c is formed on the lower edge of the locking plate 23 on one side (the side where the switching lever L-1 is provided), and the cam side 23c contacts the switching lever L-1 protruding from the opening 22a of the side portion 22. They are formed so that they touch each other.

As shown in the cross-sectional schematic diagram of FIG. 3, this switching lever L-1 protrudes from the opening 22a of the side portion 22,
The rotating piece L-2 is moved around the axis _P3 . In other words, when the movable piece L-2 presses the contact part SW-1 of the pause switch SW, it turns ON,
If the pressure is released, it will be in the OFF state.

Next, the insertion and removal operations using the lock device having the above-described structure will be explained with reference to FIGS. 4 to 6.

In order to simplify the explanation, the insertion and removal operations on the locking plate 23 of the side portion 22 from which the switching lever L-1 of the POS switch SW protrudes will be described, and the insertion and removal operations on the other side will be omitted.

First, the operation of pulling out the device main body 2 from the inner case 1 will be explained.

As shown in FIG. 4, the device main body 2 is inserted into the inner case 1 at a predetermined position, and at this time, the tip 23a of the locking plate 23 is inserted into the locking hole 13 of the inner case 1. It has become a state. However, the cam side 23c is not in contact with the switching lever L-1, that is, the pause switch SW is not in contact with the switching lever L-1.
It is in the OFF state. Next, as shown in FIG. 5, when the handle 3 is pulled up toward you centering on the support shafts P ₁ and P ₁ , the guide groove 23b moves along the guide pin 24 and the tip 23a of the locking plate 23 is locked. It is removed from the hole 13. Moreover, the cam side 23c pushes down the switching lever L-1 via the shaft _P3 , and the movable piece L-2 moves to the contact part SW- of the pause switch SW.
Press 1. This causes the pause switch SW to
It is in the ON state and is in a temporarily stopped state, for example, the pressure of the pinch roller against the cab stan shaft is released, and the running of the tape is interrupted or stopped.

In this state, as shown in Fig. 6, by pulling up the handle 3 further and pulling it out toward you, the power connector (not shown) will be disconnected, and the device body 2 will be disconnected.
is completely pulled out from the inner case 1.

On the other hand, when inserting the device main body 2 into the inner case 1 in the opposite manner to the above operation, the operation is the opposite of the above-mentioned pulling out operation (state in Fig. 6 → state in Fig. 5 → state in Fig. 4) When this is done, the locking plate 23 rises along the guide pin 24, and the tip 23a is fitted into the locking hole 13 of the inner case 1. Then, the power connector is connected and the device main body 2 can be driven.

To pull out the handle 32 of the handle 3 all the way to the front with the device main body 2 inserted into the inner case 1, press the protrusion 31a provided on the arm 31 and pull the handle 3 forward slightly. 32 can be easily grasped. Similarly, it is also possible to pull out the arm 31 via a hook 31b protruding from the front surface thereof.

(Effects) The locking device configured as described above can be operated in conjunction with the handle to perform insertion/removal operations and to switch the pause switch. It can be easily removed from the inner case, and when inserted into the inner case, each drive mechanism inside the device is on standby, making it easy to insert and remove without damaging the various mechanisms inside the device. It will be excellent. Therefore, there is no need to take the trouble of removing it from the dash board, making it an effective locking device for theft prevention.
