Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an object mounting structure for fixing an object such as a vehicle-mounted radio to a base using a tightening member such as a screw.

[Technical background of the invention and its problems]

For example, when an on-vehicle radio is attached to the bottom of a trunk room, this is conventionally done as shown in FIG. 1, for example. That is, the support fitting 1 is first fixed to the bottom of the trunk as a base with screws 3, and then the engagement pin 2 of the radio device 2 is attached to the hook-shaped engagement protrusions 11 provided on both sides of the support fitting 1.
1, the radio 2 is locked.
In this state, as shown in an enlarged view in FIG. Machine 2 is being installed.
Therefore, with such a structure, the radio device 2 can be stably held against vibrations and shocks.
Moreover, it has the advantage of being extremely easy to install and remove by simply installing and removing 41 screws.

However, on the other hand, since anyone could easily remove it, there was a high risk of theft, which was not desirable in terms of crime prevention.

On the other hand, it has been proposed that a locking mechanism is attached to the radio 2, and the radio 2 is fixed by engaging the lever of this mechanism with the support metal fitting 1. However, although this type of structure improves security, it also causes rattling between the radio 2 and the support 1, and increases the locking operation force due to friction between the foot lever and the support 1. . For this reason, the stability of the mounting state was low and the operability was poor.

[Purpose of invention]

An object of the present invention is to provide an object mounting structure that can reliably protect against theft without impairing operability or stability of the mounted state.

[Summary of the idea]

In order to achieve the above object, the present invention covers the tightening member with a casing having a hole for operating the tightening member, and a lock is provided in the casing, and the lock acts as an operating part. The member is attached and the blocking member is moved by a locking operation to isolate the space between the operating hole and the tightening member, thereby making it impossible to remove the tightening member.

[Example of idea]

FIG. 3 shows a mounting structure in an embodiment of the present invention in which a radio device is applied as an object.
In this figure, the same parts as those in FIG. 1 are given the same reference numerals and detailed explanations will be omitted.

A locking device 5 is provided on the front side of the radio 2 . FIGS. 4 and 5 a to 5 c show the configuration. In the figure, a housing 52 containing a lock 51, that is, a key box 52, is fixed to the front panel of the radio 2. This key box 52 is
The operating portion (screw head) 4a of the screw 4 is housed therein, and a hole 53 for tightening the screw 4 is provided in the front surface facing the operating portion 4a. On the other hand, a blocking piece 54 is attached to a rotating shaft 51a serving as an operating portion of the lock 51. When the lock 51 is rotated by the key 55, the blocking piece 54 rotates in the direction of the arrow O-O' in response to the rotation operation, and connects the hole 53 provided in the key box 52 with the screw. 4 and the operating section 4a.

Therefore, in order to attach a radio device with such a structure, first attach the engagement pin 21 to the locking protrusion 11 on the support fitting 1 attached to the base (not shown).
The radio device 2 is locked by engaging them respectively. Next, the screw 4 is inserted through the hole 53 of the key box 52, and the screw 4 is screwed into the screw receiving part 13 of the support metal fitting 1 using the tool 56, thereby fixing the radio device 2 to the support metal fitting 1. Finally, the lock 51 is operated with the key 55, thereby rotating the blocking piece 54 in the direction of the arrow O' to block between the tightening operation hole 53 and the operating part 4a of the screw 4, Finish the installation.

Because of this configuration, even if the tool 56 is inserted through the tightening operation hole 53 and an attempt is made to operate the screw 4 after installation, the insertion of the tool 56 is blocked by the blocking piece 54 and the tool 56 cannot reach the screw 4. Therefore, unauthorized removal of the radio device 2 is reliably prevented. Therefore, crime prevention can be improved. Further, since the radio device 2 is fixed in a very strong state by tightening the screws 4, it is possible to maintain a stable mounting state without wobbling or falling off during use. Furthermore, since the locking operation and the tightening operation of the screw 4 can be performed separately and independently, compared to the conventional locking mechanism in which the locking mechanism is fixed by engaging the lever with the support metal 1 side. , the locking operation force is small, and operability can be improved. In addition, since only a small locking operation force is required, the occurrence of problems that tend to occur with the above-mentioned conventional mounting structure, such as when the locking operation is performed but the locking is not actually completed, is reduced. As a result, a highly reliable structure for crime prevention can be provided.

Note that the present invention is not limited to the above embodiments. For example, in the above embodiment, the hole 5 for tightening operation
Although the screw 4 is inserted from 3 and tightened and fixed, a stopper may be provided at a portion corresponding to the neck of the screw 4 to prevent the screw 4 from falling out from the front panel of the radio device 2. In this way, it is possible to prevent the screw 4 from being lost and to make the operation easier. Further, the blocking piece 54 is not only tongue-shaped as in the above embodiment, but also has a fan-shaped hole for tightening operation, and this hole faces the hole 53 provided in the key box 52 when removing a screw. It may be configured as follows. Further, depending on the structure of the lock 51, the blocking member may not only rotate but also slide, and the structure of the lock, the shape of the key box, the type of tightening member, the type of object to be attached, etc. Various modifications can be made without departing from the gist of the invention.

[Effect of idea]

The present invention covers the operation part of the tightening member with a housing having a hole for tightening operation, and a lock is provided in this housing, and a blocking member that operates as an operating part is attached to the lock. When operated, the blocking member is moved to block the operation hole from the operating portion of the tightening member, thereby preventing the tightening member from being removed.

Therefore, according to the present invention, it is possible to provide a mounting structure for an object that has excellent operability and stability of the mounted state, and can reliably protect against theft.
