Description

[Detailed description of the invention] (Field of industrial application) 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 for 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.

(Prior Art) The speaker box of a car stereo system or the like is often installed at the rear of the vehicle interior, but for example, in a high-roof passenger car, the speaker box can be installed along the lower surface of the roof. In addition to making it possible to effectively utilize the space inside the vehicle, it is also possible to improve the acoustic effect by increasing the volume of the speaker box. 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.

(Problem to be solved by the invention) By the way, in a locking device for such a rotating speaker box, generally, when the speaker box is about to rotate downward, a claw engages with an engaging part on the vehicle body side. A simple structure that prevents rotation is used. Such a locking device usually has some play in vertical rotation due to assembly problems. Therefore, even when the above-mentioned speaker box for both inside and outside the car is locked to the car body in the inside use position, there is some play in the upper part. They cause various negative effects, such as rattling, making noise, and sometimes even breaking.

The present invention was developed in view of these problems, and its purpose is to provide a rotating speaker box that is locked to the vehicle body by a locking device in a substantially horizontal in-vehicle usage position along the underside of the roof. The object of the present invention is to enable the vehicle to be held fixed without wobbling while the vehicle is running.

Another object of the present invention is to ensure that the speaker box fixing and holding device is set securely when the vehicle is running.

(Means for solving the problem) In order to achieve this object, the present invention includes an actuation rod that comes into contact with the tailgate and slides under pressure when the tailgate opens and closes the rear opening of the vehicle body. The cam mechanism is actuated by the sliding movement of the actuating rod. The cam mechanism is adapted to generate a force that pushes up the speaker box when it is in the position of use inside the vehicle.

(Function) With this structure, when the speaker box is in the in-vehicle use position and the tailgate is closed, the actuating rod is pressed and slid, and the cam mechanism is actuated. The cam mechanism then acts to push the speaker box up towards the underside of the vehicle roof, so the speaker box is pushed toward the underside of the roof and is held fixed without wobbling while the vehicle is running. .

The tailgate is always closed when the vehicle is running. Therefore, this speaker box fixing and holding device is always activated when the vehicle is running.

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

Figures 1 and 2 show an embodiment of a fixing and holding device for a rotary speaker box according to the present invention.
FIG. 1 is a schematic side view thereof, and FIG. 2 is a perspective view of its main parts. 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. In the space between the left and right sides of the storage box 10 and the roof 4, support brackets 11a, 11b, and 11c are provided in alignment in the front and rear direction.
The actuating rod 12 is supported by 1c so as to be slidable in the front-rear direction, that is, in the axial direction. The actuating rod 12 is provided with stoppers 12a, 12b between two rear support brackets 11b, 11c, and a spring 13 is provided between the stoppers 12a, 12b. Therefore,
The actuating rod 12 is made expandable and retractable by this spring 13. Further, a return spring 14 is installed between the rearmost support bracket 11c and the rear end 12c of the actuating rod 12, and this return spring 14 provides a constant rearward pressing force to the actuating rod 12. is now being added. When the rear end portion 12c of the actuating rod 12 is most retracted, that is, when the rear stopper 12b is at the rearmost support bracket 1,
When in contact with 1c, it protrudes rearward from the rear opening 3 of the vehicle body.

A wedge-shaped cam member 15 inclined forward is provided at the front end of the actuating rod 12. On the other hand, the speaker box 5 has its cam member 15
A pin 16 that engages with is provided so as to protrude from both sides. Therefore, when the actuating rod 12 slides forward, the cam member 15 engages the pin 16 and pushes the speaker box 5 upward. That is, in this embodiment, these cam members 15 and pins 1
6 constitute a cam mechanism 17 that applies a pushing force to the speaker box 5.

A buffer 18 made of an elastic material such as rubber is attached to the back of the speaker box 5.
When the speaker box 5 is pressed upward, the buffer 18 comes into contact with the inner surface of the storage box 10 to absorb the pressing force and prevent damage to the speaker box 5. In addition, the storage box 10 includes a speaker box 5.
A notch 10a is provided through which the pin 16 passes when the pin 16 rotates in the vertical direction.

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, park the car 1 and move the tailgate 2 upward as shown by the imaginary lines in FIGS. 1 and 3. to open the rear opening 3 of the vehicle body. Then, the actuating rod 12 slides rearward due to the elasticity of the return spring 14, and its stopper 12b abuts against the support bracket 11c, causing the rear end 1 of the actuating rod 12 to slide backward.
2c is held at a position protruding rearward from the rear opening 3 of the vehicle body. Then, as the actuating rod 12 retreats, the cam member 15 separates from the pin 16 of the speaker box 5. When the cam member 15 retreats in this manner, the speaker box 5 is allowed to rotate downward. Then, 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 imaginary 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 12c 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 is activated by the return spring 14.
The cam member 15 slides forward against the force, and the cam member 15 comes to engage with the pin 16 of the speaker box 5. At this time, the spring 13 provided on the actuating rod 12 contracts, and its elasticity pushes the cam member 15 forward. In this way, the actuating rod 12
As the cam member 16 is pushed forward and slides, the cam member 16 is pushed forward, and the pin 16 and therefore the speaker box 5 are pushed upward by the cam action. . As a result, the speaker box 5 is pressed against the inner surface of the storage box 10 via the buffer 18, and is fixedly held with no play therebetween.

Therefore, even if the automobile 1 is driven in this state, the speaker box 5 will not rattle due to vibrations during driving. Since the pin 16 of the speaker box 5 is supported by the cam member 15 from below, even if the lock device 7 should come off, it will be prevented from falling. Furthermore, since the speaker box 5 is pushed up, it can be reliably locked even if the locking device 7 is in a half-locked state.

In this way, the actuating rod 12 is pressed and slid by the tailgate 2, which is always closed when the vehicle is traveling, and the speaker box 5 is thereby fixedly held. The speaker box 5 cannot be lowered as long as the tailgate 2 is closed. Therefore, it is possible to prevent the speaker box 5 from being erroneously lowered while the vehicle is running, thereby obstructing the rear view.

Furthermore, since each member such as the actuating rod 12 is arranged in a dead space between the storage box 10 and the roof 4, the effective space in the vehicle interior 9 is not occupied by it, and the appearance is impaired. There's no chance of it happening.

In addition, in the above embodiment, the actuating rod 12
Cam member 15 and speaker box 5 attached to
A cam mechanism 17 that applies a pushing force to the speaker box 5 is constructed by a pin 16 provided on the speaker box 5. A roller is attached to the tip of the actuating rod 12, and a cam surface that engages with the roller is attached to the tip of the actuating rod 12. By providing the cam mechanism 17
can also be configured.

Further, the return spring 14 is not necessarily necessary, and the actuating rod 12 may be manually moved back when lowering the speaker box 5. In this way, even when the tailgate 2 is opened, the cam mechanism 17 remains in a state supporting the speaker box 5.
Inadvertent lowering of the speaker box 5 is prevented.

(Effects of the invention) As is clear from the above explanation, according to the invention, the actuating rod is pressed and slid by the tailgate, which is always closed when the vehicle is running, and the cam is moved by the sliding of the actuating rod. Since the mechanism is actuated to push up the speaker box, the speaker box is pressed against the vehicle body side and fixed, and is held without wobbling during driving. Moreover, since the cam mechanism is activated simply by closing the tailgate, there is no need to forget to set the fixing and holding device.
