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]

BACKGROUND OF THE INVENTION Conventionally, mounting devices as shown in FIGS. 1A and 2B and 2A and 2B have been generally used to secure an in-vehicle radio to a dashboard or trunk of an automobile. 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 dash board 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 hook-shaped portions 2a provided on both sides of the board 2 and tightening the presser plate 3 with screws 4.

In addition, in the configuration shown in FIG. 2, in addition to the protruding portion 1a and the hooked portion 2a, the bottom of the radio is provided with hooked portions 1b and 1.
c again on the mounting board 2 side, the hook-shaped parts 1b, 1c.
hook-shaped portions 2b adapted to engage with each other;
2c, and using these engaging means, the radio 1
is fixed to the mounting board 2. In addition, in the configuration shown in FIG. 2, in order to prevent theft of the radio 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. When the handle 6 of the board 2 is rotated, the locking piece 6 protrudes and is locked in the groove 8 of the board 2.

[Problem that the invention seeks to solve]

By the way, in-vehicle radios are required to satisfy the following conditions, especially from the viewpoint of theft prevention. In other words, (1) The radio must be able to be locked when the occupant leaves the vehicle and cannot be removed without the key.

(2) When the occupant leaves the vehicle, the radio must be easy to remove and carry, if necessary, and it must also be easy to install.

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

However, conventional mounting devices are
It did not satisfy all of the conditions (3) to (3).
That is, the configuration shown in FIG. 1 does not satisfy conditions (1) and (3) above, and the configuration shown in FIG. 2 has a drawback in point (2) above. In other words, the configuration shown in FIG. 2 has the disadvantage that a large force is required to attach and detach the radio device 1. In order to eliminate this disadvantage, the configuration shown in FIG.
If the respective fittings with a, 2b, and 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 mounted on the mounting board, there is provided a means for positioning the radio device and for allowing rotation of the radio device with respect to the mounting board, and a means for positioning the radio device 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). ), and a means for maintaining this locked state, the above-mentioned (1) to (3) can be achieved.
It satisfies all of the conditions.

[Effect]

With this configuration, after positioning the radio on the mounting board, the radio can be mounted on the board by simply rotating the radio, for example, clockwise, and the mounted radio can be mounted on the board, for example. It can be removed by simply rotating it 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. 3 to 7.

FIG. 3 is a perspective view of the radio device 11 and the mounting board 12 viewed from below, and in the center of the bottom surface of the radio device 11, which is the mounting surface to the board 12.
A cylindrical protrusion 11a serving as a shaft having an axis perpendicular to the bottom surface is provided, and correspondingly, a circular protrusion 11a serving as a bearing portion into which the cylindrical protrusion 11a can be fitted is provided at the center of the mounting board 12. A hole 12a is formed. Further, pins 13 are installed at both ends of the bottom of the radio 11, and this pin 13 is the fourth pin.
As shown in FIG.
An annular groove 13c having a height d ₁ is formed between the groove 13c and the upper surface of the groove 3a. 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 as shown in FIG. 4A, the height d of the annular groove 13c of the pin 13 is It is curved in the vertical direction with a height d ₂ greater than ₁ .

A lock 15 is attached to the radio 11, and 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, the radio 11 is connected to the bolt 17.
When mounting on the board 12 fixed to a vehicle, first align the cylindrical protrusion 11a of the radio 11 with the circular hole 12a of the mounting board 12, and then remove the protrusion 11a.
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, radio 11
When force is applied counterclockwise when viewed from the bottom side, the radio 11 rotates around the axis of the cylindrical protrusion 11a, and the spring plate 14 is elastically fitted into the annular groove 13c of the pin 13. When the state shown in FIGS. 5 and 7 is reached, and the radio device 11 is viewed from the bottom side, further rotation of the radio device 11 in the counterclockwise direction and a direction parallel to the axis of the cylindrical protrusion 11a are observed. The radio device 11 is locked at a predetermined position on the board 12 in such a manner that movement thereof is prevented. In this case, the annular groove 1 of the pin 13
The spring plate 14 fitted into the inside of the spring plate 3c is deformed as shown in FIG.
Since it acts in the direction of elastic pressure bonding, the radio device 11 can be mounted on the mounting board 12 without any play.

Next, the key 15a of the lock 15 attached to the radio 11
By rotating the locking piece 16 in the locking direction, the locking piece 16
protrudes and engages with the mounting board 12, thereby preventing the radio device 11 from being rotated clockwise (as viewed from the bottom side) from the states shown in FIGS. 5 and 7.

Radio device 1 installed in a car in this way
1 from a car, first unlock the lock 15 using the key 15a and retract the locking piece 16, then rotate the radio 11 clockwise when viewed from the bottom to release the pin 13 and the spring. It is only necessary to lift the radio device 11 after releasing the engagement with the plate 14.

In addition, in the present embodiment described above, as positioning and pivoting means between the radio device 11 and the board 12, the cylindrical protrusion 11a as a shaft portion is provided on the radio device 11 side, and the cylindrical protrusion 11a as a bearing portion is provided on the board 12 side. Although the circular holes 12a are respectively formed, it goes without saying that it is also possible to have a configuration in which a cylindrical protrusion is formed on the substrate 12 side and a circular hole is formed on the radio device 11 side.

〔Effect of the invention〕

As is clear from the above explanation, 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.
