Description

[Detailed Description of the Invention] This invention relates to a mounting device suitable for a vehicle-mounted radio device.

A sheet metal mounting frame called a mount is generally used to mount a radio device inside a car. A typical conventional example will be described with reference to FIGS. 1 and 2. A mount 1 consists of a substantially U-shaped sheet metal frame including a pair of left and right side plates 2, 2 parallel to each other. , on the side plates 2, 2,
Guide groove 4 formed in the side wall of the housing of the radio device 3
Guide rails 5, 5 that slidably engage with are provided over substantially the entire length thereof. Also,
A plate spring 7 is attached as a stopper to one of the side plates 2, 2, and has a locking hole that fits into a projection 6 protruding from the side wall of the housing of the radio device 3. This mount device has a simple structure and is certainly inexpensive, but in order to mount radio device 3, it is necessary to insert the casing from the front of mount 1 and slide it about 150 mm, which makes it difficult to fit inside a relatively narrow car. It was difficult to attach and detach the device. Furthermore, since the stopper is only provided on one side, there is a risk that the stopper will come off if force is applied to the radio 3 in the opposite direction to the stopper. There are disadvantages in that the mounting direction is limited, such as the mount 1 not being able to be mounted vertically. Furthermore, when releasing the lock of the stopper made of the leaf spring 7, if excessive force is applied to the stopper, the leaf spring 7 may buckle and become deformed.

This idea was created in view of the above-mentioned drawbacks of the conventional technology, and its purpose was to allow the radio to be mounted with a small amount of sliding, and to prevent excessive operating force from being applied to the stopper made of a leaf spring. An object of the present invention is to provide a wireless device mounting device.

Hereinafter, embodiments of this invention will be described in detail with reference to FIGS. 3 to 6.

This mounting device includes a mount 1 for mounting the radio device 10 near the dashboard of a car, for example.
1. Note that the radio device 10 is provided with protrusions and guide grooves similar to those shown in FIGS. 1 and 2. That is, although FIG. 6 only shows one side wall of the housing of the radio device 10, each side wall of the housing is provided with a protrusion 12 on the front side in the direction of pushing into the mount 11. Moreover, a guide groove 13 parallel to the pushing direction is formed at the rear of this protrusion 12.
In this case, the rear end of the guide groove 13 is widened in a V-shape toward the back wall of the housing of the radio device 10.

The mount 11 includes a flat substrate 1
4, and a pair of left and right side plates 15, 1 formed parallel to each other by bending both ends of the substrate 14 at approximately right angles.
5. In FIG. 3, which shows a perspective view of the mount 11, if the left side is the front side when installing the radio device 10, the side plate 1 of the mount 11
Holding parts 16, 16 for holding the radio device 10 via the projections 12 are provided on the front sides of the side plates 15, 15, and on the other hand, on the rear side of the side plates 15, 15, widened parts of the guide grooves 13 are provided. Guide rails 17, 17 are formed to engage with 13a. holding part 16,
16 are provided with engagement grooves 18, 18 formed so as to engage with the projections 12 along the pushing direction from the front side of the radio device 10 in the pushing direction. In this case, as is clear from FIGS. 5 and 6, the upper edge 18a of each engagement groove 18 is shorter than its lower edge 18b, so that the engagement groove 18 is It is shaped like a letter.
However, the upper edge and lower edge here are based on the direction in which the mount 11 is attached to a dash board, etc. For example, unlike the drawings of this embodiment, if the mount 11 is upside down, 18a is the lower edge. , 18b, which is longer than that, is the upper edge. That is, in this invention, the widened portion 13b of the guide groove 13 is hooked onto the guide rail 17, and the radio device 10 is rotated toward the board 14 using the expanded portion 13b as a fulcrum, so that the protrusion 12 is connected to the engagement groove 18. It is set in a position that matches the open end, and then radio 1
The projection 12 is configured to engage in the engagement groove 18 by pushing in the engagement groove 18.

A leaf spring member 19 is attached to each of the holding portions 16 to cover the engagement groove 18 from the outside. This leaf spring member 19 is made of a tongue piece having a mounting base 19a fixed to the rear end side of the holding part 16, but in this case, a predetermined gap is left between the mounting base 19a side and the holding part 16. The distal end portion 19b extends outward from that portion and is bent so that the gap with the holding portion 16 gradually narrows. And its tip 1
9b has a protrusion 1 pushed into the engagement groove 18.
A stopper 20 for locking 2 is provided in a protruding manner.

This device also includes a release lever 21 that forcibly deforms the leaf spring member 19 toward the outside of the mount 11 to release the locking function of the stopper 20 with respect to the protrusion 12. This release lever 21 is connected to the side plate 1 as illustrated in FIG.
It is slidable in the front-rear direction via a long hole 23 that engages with a guide pin 22 implanted in the
And the tension spring 2 interposed between the side plate 15
4, it is held in the rear inoperative position. In this case, the tension spring 24
It is provided between the protrusion 15a of No. 5 and the protrusion 21a connected to the release lever 21. and,
An actuation plate 25 inserted between the holding portion 16 and the plate spring member 19 is connected to the release lever 21 . The actuation plate 25 is provided with a U-shaped groove 26 formed so as to escape the protrusion 12 in the engagement groove 18. On the other hand, hemispherical bosses 27, 27 that make point contact with the actuating plate 25 are protruded from the tip end 19b of the leaf spring member 19.

In addition, in the mount 11, at the rear end of the substrate 14, there is a pressing plate that is bent so as to elastically abut against the back wall of the base plate 14 and urge the radio 10 forward when the radio 10 is attached. 28 are installed in series. However, it is also possible to simply bend the rear end of the board 14 at a right angle and provide an elastic body such as rubber for pressing the back wall of the radio device 10 on the inner wall side.
Further, a guide groove 29 for the free end side of the actuating plate 25 is provided at the upper end of the holding portion 16 (see FIG. 4).

Next, the operation of this invention will be explained. To install the radio 10 in the mount 11, first,
Widened portion 13 formed behind the guide groove 13
a to the guide rail 17, rotate the radio 10 toward the board 14 using it as a fulcrum,
The projection 12 is guided to the open end position of the engagement groove 18.
Then, when the radio device 10 is pushed into the mount 11, the protrusion 12 displaces the stopper 20 outward and fits over the stopper 20 into the engagement groove 18. In this way, the radio device 10 is held within the mount 11 by the holding portion 16 and the guide rail 17. In this case, the radio device 10 is urged to be pushed by the pressing plate 28, and as a result, the protrusion 12 comes into strong contact with the stopper 20, so that the radio device 10 does not shake inside the mount 11. There isn't. In this device, the guide groove 13 does not necessarily have to be as long as shown in the figure, since only the widened portion 13a side of the guide groove 13 is engaged with the guide rail 17 as described above.

Next, in order to take out the radio device 10 from inside the mount 11, the release lever 21 can be pulled toward the front against the tension spring 24. That is, the release lever 21
When the actuator plate 25 is pulled out from the rear non-operating position toward the front operating position, the actuating plate 25 slides forward and comes into contact with the bosses 27, 27, causing the tip 19b of the leaf spring member 19 to move outward. Forcibly transform towards. As a result, the stopper 20 moves to the protrusion 1.
2, the radio 10 is removed from the pressing plate 28.
It is pushed forward by the urging force of . Therefore, the user can release the release lever 21 and take out the radio 10.

As is clear from the above description of the embodiment, according to this invention, the radio is installed in the mount by hooking the rear end of the radio, rotating it, and pushing it in. It can be easily attached and detached with a sliding distance of only about 30 mm, which is extremely convenient in practice, and there are no restrictions on the mounting location of the mount as in the past. Furthermore, since the leaf spring with the stopper is not operated directly but via a release lever, there is no possibility that excessive force will be applied to the leaf spring, and the stopper will not break as in the case of conventional methods. There's no danger of it getting lost.
