Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting device for removably mounting an in-vehicle radio device in a predetermined position of a vehicle such as an automobile.

[Conventional technology]

2. Description of the Related Art Conventionally, in order to fix an in-vehicle radio in a car port or trunk, a mounting device as shown in FIGS. 1A and 2B and 2A and 2B has been generally used. That is, in the configuration shown in FIG. 1, the radio device 1 is configured to be removably attached to the mounting board 2 fixed in the danoshgoud or trunk of an automobile, and the protrusions 1a formed on the left and right sides of the radio device 1 The radio device 1 is fixed to the mounting board 2 by fitting into the hook-shaped portions 2a provided on both sides of the board 20 and tightening the presser plate 3 with screws 4.

In addition, in the configuration shown in FIG. 2, in addition to the protrusion 1a and the hooked portion 2a, hooked portions 1b and lc are provided on the bottom of the wireless device, and hooked portions 1b and lc are engaged with the hooked portions 1b and lc on the mounting board 2 side, respectively. Hook-shaped portions 2b and 2c are provided, and the radio device 1 is fixed to the control board 2 using these fixing means.

Further, in the configuration shown in FIG. 2, the purpose is to prevent theft of the radio device 1.

A lock 5 is attached to the radio 1 so that the radio 1 cannot be removed from the mounting board 2 without a key, and when the handle 6 of the lock 5 is turned, the locking piece 6 protrudes and locks into the groove 8 of the board 2. It is designed to be locked when the vehicle is entered.

[Problem that the invention seeks to solve]

By the way, in-vehicle radios are required to satisfy the following conditions, particularly from the viewpoint of theft prevention.

Namely.

(1) The radio can be locked when the occupant leaves the vehicle.

Make sure that it cannot be removed without a key.

(2) When the occupant leaves the vehicle, the radio device should be easy to remove so that it can be removed and carried as necessary, and it should also be easy to install.

(3) No tools are required when attaching or detaching the radio.

However, the conventional mounting devices are not compatible with the above-mentioned (1) to (
It did not satisfy all of the conditions in 3).

That is, the configuration in FIG. 1 does not satisfy the conditions (1) and (3) above, and the configuration in FIG.

There was a problem with point (2) above. That is, the configuration shown in FIG. 2 has a disadvantage in that a large force is required to attach and detach the radio device 1, and in order to eliminate this disadvantage, the protrusion 1a is used.

Hook-shaped parts 1b, lc and hook-shaped parts 2a, 2b on the substrate 2 side.

If the respective fittings with 2c are loose, looseness is likely to occur when the vehicle vibrates.

[Means for solving problems]

Therefore, in the present invention, when the radio device is attached to the mounting board, there is provided a means for performing one positioning action and allowing rotation of the radio device with respect to the mounting board, and a first positioning means for the radio device to be mounted around the axis of this means. The radio device is locked to the mounting board by rotating it in a direction (for example, clockwise), and in this locked state, the radio device is rotated in a second direction opposite to the first direction (for example, counterclockwise direction). ) The above-mentioned conditions (17 to (3)) are all satisfied by the means that can release the locked state by rotating the locking state and the means for maintaining the locked state.

[Effect]

With these two configurations, after aligning the radio on the mounting board, the radio can be mounted on the board by simply rotating the radio, for example, clockwise, and the radio It can be removed simply by rotating the machine, for example counterclockwise. Furthermore, it is also possible to make the radio device unremovable from the board.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 6 and 7.

FIG. 6 is a perspective view of the radio device 11 and the mounting board 12, viewed from below.
A cylindrical protrusion 11a is provided, and correspondingly, a circular hole 12a into which the cylindrical protrusion 11a can be fitted is formed in the center of the mounting board 12. In addition, pins 1 and 3 are installed at both ends of the bottom of the radio 11, respectively.
3, as shown in FIG. 4A, includes a large-diameter head 13a and a small-diameter neck 13b that connects the head 13a and the bottom of the radio 11. An annular groove 13c having a height dl is formed between the upper surface of the groove 13c and the upper surface of the groove 13c. On the other hand, a spring plate 14 is attached to the mounting board 12 at a position corresponding to the pin 13.

This spring plate 14 is formed into a bifurcated shape with a groove 14a into which the neck 13b of the pin 13 can fit, and a fourth
As shown in Figure A, the height dl of the annular groove 13c of the pin 13
It is curved in the vertical direction with a height d2 greater than the height d2.

A lock 15 is also attached to the radio 11.

When the key 15a of the lock 15 is turned from the unlocking direction to the locking direction, a locking piece 16 projects from the bottom surface of the radio 11.

In the above configuration, when the radio device 11 is attached to the board 12 fixed to the vehicle with the bolt 17.

First, the cylindrical protrusion 11a of the radio device 11 is aligned with the circular hole 12a of the mounting board 12, and the protrusion 11a is inserted into the circular hole 12a. This state is shown in FIG. 6, where the pin 13 and the spring plate 14 are in a position where they do not overlap with each other. In this state, when a force is applied counterclockwise when viewing the radio 11 from the bottom side, the radio 11 rotates around the axis of the cylindrical protrusion 11a.

The spring plate 14 is elastically fitted into the annular groove 13c of the bottle 13, resulting in the state shown in FIGS. 5 and 7.

In this case, the spring plate 4 fitted into the annular groove 13c of the bottle 13 is deformed as shown in FIG.
Since it acts in the direction of elastically compressing the mounting board 12, the radio device 11 can be mounted on the mounting board 12 without any play.

Next, by rotating the key 15a of the lock 15 attached to the radio device 11 in the locking direction, the locking piece 16 protrudes and engages with the mounting board 2, thereby locking the radio device 11 into the fifth Clockwise (viewed from the bottom side) K from the state shown in the figure and Fig. 7
Prevent it from being rotated.

When removing the radio 11 installed in the car in this way, first unlock the lock 15 using the key 15a, pull in the locking piece 16, and then look at the radio 11 from the bottom side. The radio device 11 may be lifted after rotating clockwise to release the engagement between the bottle 13 and the spring plate 14.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, it is possible to attach and detach the radio very easily without the need for any tools, and the radio can be firmly attached to a predetermined position in the vehicle. can.

Furthermore, since the radio can be locked after being installed, theft of the radio can be prevented.
