DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a speaker device for a stereo device installed in a vehicle such as an automobile, and in particular, it relates to a speaker device installed in a vehicle such as a vehicle. It can also be used as The present invention relates to a speaker device for both inside and outside of a vehicle.

(Prior Art) A speaker box for an automobile stereo system or the like is installed inside the vehicle. For example, in a high-roof passenger car, the space under the roof is used to install the speaker box almost horizontally along the underside of the roof. It is conceivable to install it in In this way, the space inside the vehicle can be used effectively, and the speaker box can have a large volume, so that the acoustic effect can be improved.

On the other hand, in the case of a hatchback car, when you go camping or having a picnic, you can park it outdoors and open the tailgate, and you can use the built-in car stereo system to listen to music outdoors. can be enjoyed. In this case, if the speaker box provided inside the vehicle can be directed toward the rear outside the vehicle, it will be more suitable for listening to music outdoors.

For this reason, in high-roof type hatchback cars, as shown in Japanese Utility Model Application No. 58-11570, for example, the speaker box is installed at the rear of the underside of the roof of the car body, and its ends are A device has been proposed that is rotatably supported in the vertical direction and can be set in two positions: an in-vehicle use position facing the interior of the vehicle and an outside use position facing the rear outside the vehicle.

In other words, when using the speaker box outside the vehicle, it is desirable to position the speaker box as close as possible to the rear opening of the vehicle body. As a result, the speaker box is located at the rear of the vehicle even when used inside the vehicle.

On the other hand, when listening to music etc. using a stereo system, it is generally desirable to have the speaker box located near the listener. It is desirable that the vehicle be installed near the vehicle interior, that is, closer to the center of the vehicle interior.

For this reason, it is difficult to satisfy the demands for both interior and exterior use with a speaker box that is rotatably supported on the vehicle body.
In order to prevent interference with the seat etc. when the speaker box rotates, the width of the speaker box must be small in the front and rear direction, and its volume cannot be made sufficiently large. Therefore, the advantages of installing the speaker box on the lower surface of the roof cannot be fully utilized.

Furthermore, with the speaker box supported on a fixed portion of the vehicle body, its position cannot be adjusted according to the passenger's preference.

The present invention has been made in view of the above circumstances, and its purpose is to support a speaker box at a position and angle most suitable for listening inside the vehicle when used in a vehicle;
When used outside the vehicle, the device is supported toward the rear outside the vehicle at a position close to the rear opening of the vehicle body, and also does not interfere with the seat or the like during movement.

(Means for solving the problem) In order to achieve this object, the present invention provides a guide rail in the vehicle body that extends from the vicinity of the rear opening of the vehicle body along the lower surface of the roof to the front of the vehicle interior, and the guide rail According to
A support frame supporting the speaker box is movably supported. This support frame is fixed at any position on the guide rail by a brake device. In addition, the speaker box
It is rotatably supported on a support frame by a horizontal axis in the left-right direction of the vehicle body, and is fixed by a locking device at any angular position around the horizontal axis.

(Function) When using the speaker device configured in this way for inside a car, the support frame is moved along the guide rail to the position most suitable for the front seat or rear seat occupant, and then the brake system is used to The speaker box is then rotated about a horizontal axis to adjust the direction of the speaker and then fixed in its angular position by a locking device.

When using this speaker device outside the vehicle, move the support frame to the rearmost end of the guide rail near the rear opening of the vehicle body and fix it there, then rotate the speaker box rearward so that the speaker can be used outside the vehicle at the rear. Fix it in the facing position.

During this time, the support frame is supported almost parallel to the guide rail, and the speaker box is moved while remaining almost parallel to the support frame, so the speaker box may interfere with the seat etc. during the movement. do not have.

(Example) Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 is a schematic side view of an automobile equipped with the speaker device, and FIG. 2 is a schematic side view of a car equipped with the speaker device. The front view and FIG. 3 are bottom views of the speaker box portion. Moreover, FIG. 4 is an enlarged side view of the brake device provided in the speaker device, and FIG. 5 is an enlarged side view of the lock device.

As is clear from FIG. 1, this automobile 1 is a high-roof type hatchback vehicle, and an opening 3 at the rear of the vehicle body is opened and closed by a tailgate 2 that is rotated in the vertical direction. On both sides of the lower surface of the roof 4 of the automobile 1, a pair of left and right guide rails 6. 6 is provided. Second
, 3, this guide rail 6 is channel-shaped, and a pair of front and rear rollers 7.7 are guided by the groove. This roller 7.7 supports a pair of left and right support frames 9, 9 that support the speaker box 8 via a pair of front and rear shafts to, to which are protruded from the outer surface of the support frames. 9.9 is moved in the longitudinal direction of the vehicle along the guide rail 6.6 in a substantially parallel manner.At approximately the center of the left and right outer surfaces of the 6-speaker box 8, there is a horizontal A shaft 11.11 is fixedly installed, and by inserting this horizontal shaft 11.11 into a shaft hole 12.12 provided in the center of the support frame 9.9, the speaker box 8 is supported. It is supported to be rotatable in the vertical direction with respect to the frame 9. In this way, the speaker box 8 is mounted on the support frame 9
along the guide rail 6,
It is adapted to be rotated around a horizontal axis 11. Inside the speaker box 8, there are a pair of speakers 1 on the left and right.
3.13 is provided. Power is supplied to the speaker box 8 from the automobile stereo device via an appropriate telescopic cable.

A brake shaft 14 is pivotally supported on the outer surface of the support rail 9 in proximity to one of the rollers 7 . This brake shaft 1
The tip side of the brake shoe 4 extends into the groove of the guide rail 6, and a brake shoe 1 made of a high-frictional elastic material is attached to the tip.

As shown in the figure, it has an almost elliptical shape, and when it is in the position shown by the solid line in the figure, its both ends abut the upper and lower inner surfaces of the guide rail 6, and the support frame 9 is fixed to the guide rail 6. It is now possible to do so. In addition, when the brake shoe 1 is in the position shown by the imaginary line in the same figure,
A gap is formed between the support frame 5 and the guide rail 6 to allow movement of the support frame 9. A brake lever 16 is fixed to an intermediate portion of the brake shaft 14, and by rotating the brake lever 16 around the brake shaft 14, the brake shoe 15 is rotated. The brake lever 16 is biased by an appropriate toggle mechanism or the like so as to stop at the solid line position and the imaginary line position in FIG. 4. In this way,
A brake device 17 is configured to fix the support frame 9 at an arbitrary position on the guide rail 6.

Also, a horizontal shaft 1 fixed to the side of the speaker box 8
1 is provided with a plurality of radial locking holes 18, 18, . for,
A low pin 19 that fits into this locking hole L8 and fixes the speaker box 8 is attached. This lock pin 19 is supported in a support hole 20 formed in the support frame 9 so as to be able to move forward and backward, and is always urged by a coil spring 21 in a direction to engage with the locking hole 18 of the horizontal shaft 11. . By pulling down the knob 22 against the coil spring 21, the lock pin 19 is released from the locking hole 18 of the horizontal shaft 11, allowing the speaker box 8 to rotate. In this way, the locking device 23 that fixes the speaker box 8 at an appropriate angular position around the horizontal axis 11 is configured by the low pin 19, the locking hole 18, and the like.

Next, the operation of the speaker device configured as described above will be explained.

When listening to music etc. outside the car, park the car 1, rotate the tailgate 2 upward, and open the rear opening 3 of the car body.
Then, the brake lever 16 is rotated to the position shown by the imaginary line in FIG. 4, the brake is released, and the support frame 9 is moved to the position shown by the dashed dot line in FIG. Return the lever 16 to the position indicated by the solid line in FIG. 4 to fix the support frame 9 to the guide rail 6, and pull down the knob 22 of the locking device 23 to remove the lock pin 19 from the locking hole 18 of the horizontal shaft 11. . As a result, the horizontal shaft 11 of the speaker box 8 can be rotated relative to the shaft hole 12 of the support frame 9, so the speaker box 8 can be rotated significantly backwards as shown by the arrow in FIG. Point 13 toward the rear of the vehicle. When you let go of the knob 22 in this state, the lock pin 19 is moved to the horizontal axis 1 by the elasticity of the coil spring 21.
The speaker box 8 is fitted into the locking holes 18 facing each other.
is fixed to the support frame 9. In this way, the speaker box 8 is set at a position suitable for use outside the vehicle, and it becomes possible to enjoy music etc. even outdoors using the automobile stereo device.

When the automobile 1 is running normally, the speaker box 8 is used inside the vehicle. At this time, the speaker box 8 is
By moving the support frame 9 in the front-rear direction along the guide rail 6 and fixing it at an appropriate position using the brake device 17, the position can be adjusted as desired. Further, the direction of the speaker 13 can be adjusted by releasing the locking device 23, changing the angle with respect to the support frame 9, and locking it again at an appropriate angle. Therefore, for example, as shown by the solid line in FIG. 1, by fixing the support frame 9 at the center of the passenger compartment 5 and holding the speaker box 8 almost horizontally, music etc. can be heard from above the occupants' heads. The support frame 9 can be moved to the front of the passenger compartment 5 as shown by the two-dot chain line, and the speaker box 8 can be tilted rearward so that music etc. can be played from the front. By positioning the frame 9 at the rear end of the passenger compartment 5 and directing the speaker box 8 forward, it can be used as a rear speaker. You can make it possible to

During such movement of the speaker box 8 in the longitudinal direction, the speaker box 8 is held in a state substantially parallel to the support frame 9, that is, in a state along the lower surface of the roof 4. Therefore, there is no need to provide a special space for its movement.Moreover, the rotation of the speaker box 8 for use outside the vehicle is performed at the rear end of the passenger compartment 5, and the radius of rotation is smaller than that of the speaker box 8. It is a small box centered on a horizontal axis 11 provided approximately at the center of the left and right outer surfaces of the box 8. Therefore, there is no risk of interference with the seat or the like due to the rotation.

The brake device 17 for fixing the support frame 9 to the guide rail 6 can be used to prevent sudden stops or starts of the vehicle.
It can also withstand vibrations while driving,
Any device may be used as long as it can be easily fixed and released, and various types can be used in addition to those in the above-mentioned embodiments. FIG. 6 shows such a brake device 1
This shows another example of No. 7.

In this embodiment, a bracket 24 is provided on the lower surface of the left and right support frames 9.9 in the vicinity of one of the rollers 7 and extends to the lower surface of the guide rail 6. A push screw 26 to which a brake shoe 25 made of a frictional elastic material is attached is screwed. When changing the position of the support frame 9 on the guide rail 6, the knob 27 of the push screw 26 is rotated to separate the brake shoe 25 from the lower surface of the guide rail 6.

After moving the support frame 9 to a desired position, the knob 27 is rotated again to press the brake shoe 25 onto the guide rail 6.

The locking device 23 for fixing the speaker box 8 to the support frame 9 at an appropriate angular position is not limited to the one described in the above-mentioned embodiments. FIG. 7 shows a locking device 23 using a click mechanism. This shows another example.

In this embodiment, a horizontal shaft 11 protruding from approximately the center of the side surface of the speaker box 8 in the left-right direction is formed with a slightly large diameter, and a predetermined interval is placed around the horizontal shaft 11. A large number of hemispherical recesses 28, 28. ... is formed. A radial hole 29 is provided in the inner peripheral surface of the shaft hole 12 of the support frame 9 that supports the horizontal shaft 11. is pressed toward the hemispherical recess 28 of. Therefore, speaker box 8
is fixed at a position where one sphere 30 fits into the hemispherical recess 28.

Since the horizontal axis 11 is provided approximately at the center of the side surface of the speaker box 8, even if an external force is applied to the entire speaker box 8, a large rotational moment will hardly act around the horizontal axis 11. Therefore, even with such a lick mechanism, rotation of the speaker box 8 can be sufficiently prevented.

(Effects of the Invention) As is clear from the above description, according to the present invention, a guide rail is provided that extends from the vicinity of the rear opening of the vehicle body along the lower surface of the roof to the front of the vehicle interior, and a support guided by the guide rail is provided. The frame can be fixed at any position, and the speaker box is pivotally supported on the support frame so that it can be fixed at an appropriate angular position, so when using this speaker device inside a car,
The speaker can be set at the optimal position and angle according to the occupant's preference, and when used outside the vehicle, it can be supported in a position close to the rear opening of the vehicle so that the speaker faces outside the vehicle. can.

Therefore, it is possible to obtain a speaker device that is fully satisfactory both for use inside the car and for use outside the car.

The speaker box can be moved parallel to the roof while remaining in a horizontal position, eliminating the risk of interference with the seatback or luggage in the trunk. At the same time, by making the speaker box large in volume, the sound effect can be improved.
