The speaker box 1 to the mounting portion 3 by inserting the nut 7 into the hole 4 of the mounting portion 3 of the rear tray or the like and the hole 6 of the tray panel 5 and screwing the nut 7 into the mounting screw 2 protruding on the back surface of the tray panel 5. And a mounting device for an in-vehicle speaker, in which the mounting screw 2 is screwed and fixed to the screw 8 so that the mounting screw 2 is provided at the bottom of the speaker box 1 as shown in FIG. Was there.

(Problems to be solved by the invention) However, when mounting to the mounting portion 3 near the rear seat 9, the speaker box 1 is housed in the narrow wedge-shaped space S between the rear glass 10 and the mounting portion 3 and the mounting screw 2 is provided in the hole. The installation work to insert into 4, 6 is extremely difficult.

That is, when the depth e from the rear seat 9 to the rear glass 10 is narrow and the wedge angle θ formed by the rear glass 10 and the mounting portion 3 is small, the speaker box 1 is attached to the rear glass 10 as shown in FIG. The mounting screw 2 is attached to the mounting portion 3,
It is difficult for the mounting screws 2 to enter the holes 4 due to collisions, and in some cases, the mounting screws 2 cannot be inserted into the holes 4.

Even if the mounting screw 2 can be removed as shown in Fig. 9,
The position of the female screw 8 on the bottom of the speaker box 1 placed on the mounting portion 3 is extremely difficult to find, and therefore,
It is not easy to align the speaker box 1 so that the female screw 8 is directly above the holes 4 and 6 and screw the mounting screw 2 into the female screw 8.

To mount the box-type speaker system cabinet on the rear tray of an automobile and fix the cabinet to the rear tray with the mounting bolts, a recess is formed in the lower part of the cabinet, and the mounting is performed within the recess. The head of the bolt is pivotally supported by a pin so that the mounting bolt can be set in the recess before mounting, and the mounting bolt protruding downward from the recess can be inserted through the mounting hole of the rear tray before mounting. An in-vehicle speaker system configured as described above is known as "Shokaisho 61-168786".

According to this known technique, the mounting bolt can be retracted into the recess before mounting, and the cabinet can be handled compactly.
A technique for facilitating alignment of a mounting bolt with a hole in a rear tray and insertion operation into the hole in a narrow wedge-shaped space formed by a rear glass and a rear tray, which is the subject of this invention. Is not disclosed.

This device is a speaker box 1 in a narrow wedge-shaped space.
It is proposed in order to solve the above-mentioned conventional drawback that the mounting work of housing the mounting screw 2 and inserting the mounting screw 2 into the hole 4 of the mounting portion 3 is extremely difficult. By providing an in-vehicle speaker mounting device that is devised to facilitate the positioning of the mounting bolt to the mounting hole of the rear tray and the insertion operation into the mounting hole in the narrow wedge-shaped space formed. is there.

(Means for Solving Problems) The configuration of the present invention for solving the above-mentioned conventional problems is
In an in-vehicle speaker fixed by a mounting screw that is inserted into a mounting hole of a mounting portion on the vehicle body side, the threaded portion of the mounting screw is elastically protruded from the bottom of the speaker box in a substantially right angle shape with respect to the bottom. In addition, the mounting device for a mounting speaker is characterized in that the elastic protrusion output is set to be weaker than the own weight of the speaker box.

(Operation) When mounting the speaker box on the mounting part on the vehicle body side, the screw part of the mounting screw that elastically protruded from the bottom part of the speaker box in a substantially right angle shape is attached to the speaker box by its own weight. The speaker box that is immersed inside and does not have a protruding member from the bottom
It can be easily slid to the mounting position on the mounting portion on the vehicle body side without any resistance, and can move to a predetermined mounting position without trouble even in a narrow wedge-shaped space.

When the speaker box reaches the predetermined mounting position, the mounting screw projects from the bottom through the hole of the mounting portion, so that the mounting screw can be easily aligned with the hole.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1 which is a perspective view in which the right side portion of the speaker box 11 is cut away, the box-shaped mounting screw storage portion 12 is mounted inside the speaker box 11, and the mounting screw 13 is attached.
It is fitted in the mounting screw storage part 12 so that it can move up and down, and the mounting screw 13 protrudes from the bottom part 14 through the hole 15 of the bottom part 14 of the speaker box 11 or can be set in the mounting screw storage part 12. I have to.

As an example of a concrete structure for this purpose, as shown in the enlarged perspective view of FIG. 2, the cubic screw head 16 provided on the upper part of the mounting screw 13 is inserted into the mounting screw housing 12 so that only vertical movement is possible. The spring 17 interposed between the upper plate 12a of the mounting screw housing 12 and the screw head 16.
Is designed to push the mounting screw 13 downward. Then, as shown in FIG. 4, when the speaker box 11 is placed on the mounting portion 3, the own weight of the speaker box 11 acts on the mounting screw 13, the spring 17 is compressed, and the mounting screw 13 is mounted. It is designed to be immersed in the screw housing 12.

The lower end portion 13a of the mounting screw 13 is formed in a partially spherical shape or chamfered in order to facilitate slipping.

Next, a procedure for mounting the speaker box 11 will be described.

Put the speaker box 11 in the wedge-shaped space S between the rear seat 9 and the rear glass 10 in the direction of arrow A in FIG. 3, and then place the speaker box 11 on the mounting portion 3 as shown in FIG. Let

Since the bottom part 14 of the speaker box 11 hits the mounting part 3,
The mounting screw 13 compresses the spring 17 and is recessed in the mounting screw housing 12.

Then, the speaker box 11 is moved in the direction of arrow B toward the rear glass 10 on the mounting portion 3.

Since the lower end portion 13a of the mounting screw 13 has a spherical shape or is chamfered, the mounting box 3 is mounted on the speaker box 11
Slides with less resistance.

Eventually, as shown in FIG. 5, when the speaker box 11 reaches the predetermined mounting position, the mounting screw 13 is inserted into the hole 4 of the mounting portion 3.
