Description

[Detailed description of the invention] (Technical field to which the invention pertains) The present invention relates to a speaker device for both inside and outside the vehicle, in which a speaker box installed in the interior of a vehicle such as an automobile can also be used outside the vehicle. In particular, the speaker box can be rotated and lowered from an in-vehicle use position where it is supported almost horizontally along the lower surface of the roof to an out-vehicle use position where it is suspended and supported almost vertically near the rear opening of the vehicle body. The present invention relates to a speaker device having a rotating speaker box.

(Background of the invention and problems with the prior art) The speaker box of a car stereo system is often installed at the rear of the vehicle interior, but in high-roof passenger cars, for example, the speaker box is installed along the bottom surface of the roof. By doing so, the space inside the vehicle can be used effectively, and the speaker box can have a large volume to improve the acoustic effect. Furthermore, in the case of a hatchback vehicle, if the rear end of the speaker box is supported on a horizontal shaft in the left-right direction of the vehicle body so that it can be rotated in the vertical direction, it is possible to As shown in the above, when camping or picnicking, you can open the tailgate, rotate the speaker box downwards, and direct the speakers toward the rear of the vehicle. You will be able to enjoy music etc.

In this way, when the speaker box can be used both inside and outside the car by rotating it vertically, the speaker box is usually supported almost horizontally along the lower surface of the roof. When used in a vehicle, it is fixedly supported by a locking device on the vehicle body side. Incidentally, such a speaker box is relatively heavy and contains electrical components such as a speaker. Therefore, if the lock is not reliable, it is possible that the lock may become disengaged due to vibrations of the vehicle body while driving. If the speaker box becomes unlocked in this way, the speaker box will rapidly descend due to gravity, colliding with the rear seat headrest, luggage, etc., resulting in damage, or the speaker box may obstruct rear visibility. There is a fear.

(Purpose of the invention) The invention was developed in view of the above problems, and its main purpose is to fix the rotary speaker box to the vehicle body in an almost horizontal position in the vehicle along the underside of the roof. To prevent a speaker box from falling even if a locking device for a speaker box comes off while a vehicle is running.

Another object of the present invention is to set the speaker box fall prevention device in conjunction with the closing movement of the tailgate.

(Characteristics of the invention) In order to achieve this purpose, the invention provides an actuation rod that comes into contact with the tailgate and slides in the axial direction when the tailgate is closed, and also A stopper plate is provided that is rotatably supported between a protruding position that faces the lower surface of the speaker box and a retracted position that allows the speaker box to rotate. The stopper plate is rotated.

When the speaker box is in the in-vehicle use position,
When the tailgate is closed, the actuation rod is pressed and slid, and the stopper plate is rotated to the extended position. Therefore, in this state, even if the speaker box attempts to descend, it will come into contact with the stopper plate, so that the speaker box is reliably prevented from accidentally descending, that is, falling.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

Figures 1 to 3 show an embodiment of a fall prevention device for a rotary speaker box according to the present invention.
FIG. 1 is a schematic side view thereof, and FIG. 2 is a bottom view thereof. Further, FIG. 3 is a schematic side view of an automobile equipped with the rotary speaker box.

As is clear from FIG. 3, this automobile 1 is a high-roof type hatchback vehicle, and a rear opening 3 of the vehicle body is opened and closed by a tailgate 2 that rotates in the vertical direction. . A large speaker box 5 is attached to the rear lower surface of the roof 4 of the automobile 1. The rear end side of the speaker box 5 is pivotally supported by a horizontal hinge shaft 6 provided at the lower rear end of the roof 4.
can be rotated vertically between a substantially horizontal position shown by a solid line in FIG. 3 and a substantially vertical position shown by a phantom line in FIG. A locking device 7 is provided at the front end of the speaker box 5 for fixing the speaker box 5 to the vehicle body in a substantially horizontal position.
is provided.

Inside the speaker box 5, speakers 8, 8 are provided on the left and right sides, and when the car 1 is normally running, the speaker box 5 is at a position where it is supported almost horizontally along the lower surface of the roof 4.
That is, it is stored in the in-vehicle usage position shown by the solid line in FIG. 3, with the speaker 8 facing toward the vehicle interior 9.
It has come to be used as an in-car speaker device. When the speaker box 5 is lowered from its in-vehicle use position, the speaker box 5
is designed to be held in the lowest position by its own weight. Therefore, at this time, the speaker box 5 is suspended and supported substantially vertically by the hinge shaft 6 at the rear end of the vehicle compartment 9, that is, at a position close to the rear opening 3 of the vehicle body. and,
In such a state, that is, in the outside-vehicle usage position shown by the imaginary line in FIG. 3, the speaker 8 faces toward the rear outside the vehicle, so that it can be used as an outside-vehicle speaker device.

As is clear from FIGS. 1 and 2, when the speaker box 5 is used in the vehicle interior, the speaker box 5
It is designed to be stored in a storage box 10 fixedly attached to the lower surface of the rear roof 4. On the lower surface of the storage box 10, an actuation rod 12 is supported so as to be slidable in the front and rear direction, that is, in the axial direction, by front and rear support brackets 11a and 11b provided on both left and right sides of the speaker box 5. . This actuating rod 12 is provided with a stopper 12a located between the front and rear support brackets 11a and 11b.
A return spring 13 is compressed between the support bracket 11a and the front support bracket 11a. Therefore, the actuating rod 12 is always subjected to a backward pressing force by the return spring 13, and when it is moved back the most, that is, when it is at the stopper 12a,
When the actuating rod 12 is in contact with the rear support bracket 11b, the rear end of the actuating rod 12 is in contact with the rear opening 3 of the vehicle body.
It is starting to protrude more rearward.

The front end of the actuating rod 12 is provided with an engaging portion 12b that projects upward. On the other hand, on the lower surface of the storage box 10, which is a fixed part on the vehicle body side, a flat stopper plate 15 is rotatably mounted at its tip 15a by a vertical shaft 14 provided in front of the actuating rod 12. It is pivoted. This stopper plate 15 is provided with a long hole 15b, into which the engaging portion 12b of the actuating rod 12 is inserted so that they engage with each other. Therefore, when the actuating rod 12 slides in the axial direction, the stopper plate 15 rotates about the shaft 14 on the base end 15a side along the lower surface 5a of the speaker box 5 in the in-vehicle use position. I'm starting to do that. When the actuating rod 12 slides forward, as shown by the solid line in FIG.
When the actuating rod 12 is moved back to the farthest position, the actuating rod 12 is moved from below to the side of the speaker box 5, as shown by the imaginary line in FIG. It is designed to rotate to a distant retreat position.

In a car 1 equipped with such a speaker device for both inside and outside the car, when listening to music etc. outside the car, the car 1 is parked and the tailgate 2 is rotated upward to open the rear opening 3 of the car body. Then, the actuating rod 12 slides rearward due to the pressing force of the return spring 13, and is held at a position where its stopper 12a abuts against the rear support bracket 11b. By retracting the actuating rod 12, the stopper plate 15 is rotated to the retracted position. When the stopper plate 15 retreats in this way, the stopper plate 1 is placed below the speaker box 5.
Since the speaker box 5 is no longer located, downward rotation of the speaker box 5 is allowed. Therefore,
The locking device 7 of the speaker box 5 is removed, the speaker box 5 is rotated around the hinge shaft 6, and the speaker box 5 is lowered to the outside use position shown by the phantom line in FIG.

In this way, the tailgate 2 is opened and the speaker box 5 is suspended and supported approximately vertically by the hinge shaft 6. In this state, the speaker 8 faces rearward outside the vehicle at a position close to the rear opening 3 of the vehicle body. Therefore, by using the speaker box 5, it becomes possible to enjoy stereo music etc. even outside the vehicle using the automobile stereo device.

When you want to drive the car 1 again after enjoying music etc. outside the car, first rotate the speaker box 5 upwards, and lock the speaker box 5 with the locking device 7 in the almost horizontal use position inside the car along the lower surface of the roof 4. Fixedly supported on the vehicle body side. Next, rotate the tailgate 2 downward and open the rear opening 3 of the vehicle body.
Close. Due to this closing movement of the tailgate 2,
The tailgate 2 comes into contact with the rear end of the actuating rod 12 that protrudes rearward from the rear opening 3 of the vehicle body, and presses the actuating rod 12 forward. As a result, the actuating rod 12 slides forward against the return spring 13, causing the stopper plate 15 to rotate. Then, the tip portion 15 of the stopper plate 15
Due to this rotation, c comes to be close to and face the lower surface 5a of the speaker box 5.

When the automobile 1 is driven in this state, if the locking device 7 is not completely locked, it may become unlocked due to vibrations or the like during driving. In that case, the speaker box 5 rotates downward around the hinge shaft 6 due to its own weight and tries to fall, but at this time, the stopper plate 15 is located below the lower surface 5a of the speaker box 5, so The speaker box 5 abuts against the tip 15c of the stopper plate 15 and is supported thereby.

In this way, the stopper plate 15 is set below the speaker box 5 by the tailgate 2, which is always closed when driving, and the stopper plate 15 prevents the speaker box from falling. Become so. This stopper plate 15 may be one that can be rotated at a position slightly below the lower surface 5a of the speaker box 5 in parallel to the lower surface 5a. Therefore, the effective space within the vehicle compartment 9 is not particularly compressed by its installation, and it is easy to prevent it from interfering with other objects when rotating. Further, since the actuating rod 12 for rotating the stopper plate 15 can be provided so as to be able to slide along the lower surface of the roof 4, the space for this can be small, and the space between the storage box 10 and the roof 4 can be reduced. It can also be installed in a dead space. Furthermore, there is no need to perform any special processing on the speaker box 5 and tailgate 2.

The speaker box 5 cannot be lowered as long as the tailgate 2 is closed. Therefore, it is possible to completely eliminate the possibility of the speaker box 5 being erroneously lowered while driving and obstructing the rear view.

In addition, in the above embodiment, the tailgate 2
When opened, the actuating rod 12 slides rearward by the force of the return spring 13, and the stopper plate 15 is accordingly rotated to the retracted position. In some cases, it may be better to retract the plate 15 manually. In such a case,
The return spring 13 may be removed, or the actuating rod 12 may simply contact the stopper plate 15, so that the stopper plate 15 is rotated only when the actuating rod 12 slides forward. Bye. By doing this, even when the tailgate 2 is opened, the stopper plate 1
5 remains in the downwardly protruding position of the speaker box 5, and the speaker box 5 can be prevented from being inadvertently lowered.

(Effects of the invention) As is clear from the above explanation, according to the invention, the actuating rod is slid by the tailgate, which is always closed when the vehicle is running, and the stopper is caused by the sliding of the actuating rod. The plate is rotated so that the stopper plate protrudes to a position close to and facing the lower surface of the speaker box in the in-vehicle use position, so the locking device securely supports the speaker box while the vehicle is in use. Even if the speaker box comes off, it is possible to reliably prevent the speaker box from falling. Moreover, since the stopper plate is set at a predetermined protruding position simply by closing the tailgate, there is no need to forget to set it.
