Description

[Detailed Description of the Invention] The present invention relates to a holding device for detachably holding a main body device such as a car stereo on a fixed side of a vehicle body or the like.

A conventional holding device will be explained based on FIGS. 1 and 2. Main device 1 such as car stereo
When the main device 1 is inserted in the direction of arrow A, the engaging member 3 fixed by the mounting screw 2 engages with the engaged member 6 fixed to the fixed side 4 of the vehicle body etc. by the mounting screw 5. When the engaging member 3 is pushed in the direction of arrow B, the engagement between the engaging member 3 and the engaged member 6 is released, and the main device 1 can be removed in the direction of arrow C.

However, with such a holding device, the main device 1
Since the main unit 1 is always removable, there is a problem in preventing theft of the main unit 1 such as a car stereo.

In view of the above points, the present invention makes it impossible to remove the main device attached to the fixed side by turning off the key switch provided on the fixed side, and also provides a switch part on the engaging member to actually engage the device. The purpose of the present invention is to provide a holding device that operates to light an indicator light and issue a warning when the lock is incomplete and is in a position that allows release of engagement.One embodiment of the holding device will be described below with reference to the drawings.

In FIGS. 3 and 4, reference numeral 7 denotes a key switch provided on a vehicle body 8 as a fixed side, and the key switch 7 supplies power from a battery 10 to an operating circuit 9 of the instruments. 11 is a plunger provided in the main device 12 such as a car stereo,
It operates by being supplied with power from the operating circuit 9 via the connector 13, and displaces the movable member 14 to two different positions. Reference numeral 15 denotes an engaging member fixed to both sides of the main device 12 with mounting screws 16, and the engaging claw portion 15a is engaged with the engaged member 17 fixed to the vehicle body 8 side by the hinge action of the bent portion 15b. The pressing portion 15 of the engaging member 15 engages with the matching hole 17a.
Pressing c releases the engagement. Reference numeral 18 denotes a leaf switch fixed to the inner surface of the engaging claw portion 15a with a mounting screw 19, and
The operating circuit 20 of the main device 12 and the indicator light 21 form an electric circuit, and when one or both of the two leaf switches 18 located on both sides of the main device 12 are turned on, When the power switch 22 of the main device 12 is turned on, the indicator light 21 is turned on.

Now, assuming that the key switch 7 is on as shown in FIG. 8, the operating rod 11 of the plunger 11
a is attracted against the spring force of the spring 23,
The movable member 14 is in a position where it does not come into contact with the engaging claw 15a even if the pressing portion 15c of the engaging member 15 is pushed and the engaging claw 15a is retracted toward the main device 12 side. Therefore, by pressing the pressing portion 15c, the engagement claw portion 15a retracts toward the main device 12, so that the engagement between the engagement claw portion 15a and the engagement hole 17a can be freely released, and the main device 12 It can be attached to and detached from the vehicle body 8. Further, at this time, if the engaging claw portion 15a and the engaging hole 17a are not completely engaged as shown in the figure, the engaging claw portion 15a
The leaf switch 18 is in a state of being pushed by the user and retracted toward the main device 12 side, and the leaf switch 18 is in contact with the moving member 14. Therefore, the leaf switch 18 is on, and when the power switch 22 is turned on, the indicator light 21 lights up to warn that the main device 12 is not completely fixed.

When key switch 7 is turned off, plunger 11
The operating rod 11a is urged by the spring 23 to extend, and the movable member 14 is placed in a position where its tip face faces the inner surface of the engagement claw portion 15a with a slight distance therebetween, as shown in FIG. Moving. Therefore, even if the pressing part 15c is pressed, the engagement claw part 15a comes into contact with the moving member 14, so it hardly moves back toward the main device 12, and the engagement between the engagement claw part 15a and the engagement hole 17a is released. This makes it impossible to remove the main device 12 from the vehicle body 8.

In this way, when the key switch 7 is on, the main device 12 can be attached or detached freely, but when the key switch 7 is off, the main device 12 cannot be attached or detached, so the theft of the main device 12 is prevented. can. Further, when the main device 12 is inserted into the vehicle body 8, if the engagement between the engagement claw portion 15a and the engagement hole 17a is incomplete, the indicator light 21 lights up at the same time as the main device 12 is powered on, giving a warning. Since it emits
It is possible to prevent an accident in which vibrations caused by the running of the vehicle body 8 are applied to the main body equipment 12 and cause trouble.

As explained above, according to the holding device according to the present invention, it is possible to switch between a state in which the main device can be freely attached and detached from the fixed side and a state in which it is impossible to do so using a key switch, which helps prevent the main device from being stolen. It is extremely effective, and the switch part provided on the engagement member operates when the engagement is actually incomplete and is in a position that allows disengagement, lighting up an indicator light and issuing a warning. It is possible to prevent accidents such as when the main body equipment falls off from the main body due to the vibrations applied to the main body equipment while the vehicle is running due to running in an incomplete state, and its industrial utility value is great.
