【Example】

Hereinafter, the present invention will be explained according to the embodiments shown in FIGS. 1 to 6.

[0007] First, FIG. 1 is a partially exploded perspective view of a speaker box fixing device according to the present invention. . In FIG. 1, for example, rectangular holes 2, 2 are provided on the side surface of a speaker box 1. , arrange the L-shaped angles 3, 3 shown in FIG. 2 in the holes 2, 2, and tighten the L-shaped angles with screws 4, Penetrates the speaker box 1 through the angles 3, 3, and The screws 4, 4 are movably pivoted using the screw fasteners 5, 5 fixed on the back side. .

[0008] Note that a hole is similarly provided on the opposite side of the speaker box 1, and an L-shaped hole is formed on the opposite side of the speaker box 1. shall incorporate Guru. In addition, the edge 6 extends around the front of the speaker box 1. will be established.

[0009] As shown in FIG. 2, the L-shaped angle 3 has a fulcrum part 7 and a presser part forming a substantially right angle. 8, and the screw 4 can be inserted into the center part over the fulcrum part 7 and the presser part 8. An L-shaped hole 9 is provided, and protrusions 10, 10 parallel to each other are provided on the back surface of the fulcrum portion 7, A rectangular parallelepiped-shaped fulcrum boss 11 is provided to fit between the protrusions 10, 10, and the fulcrum boss 11 A fulcrum shaft hole 12 and a fulcrum boss screw 13 are provided in a direction perpendicular to the fulcrum shaft hole 12. . The fulcrum boss screw 13 is screwed into the screw 4.

0010 The fulcrum boss 11 is inserted between the protrusions 10 and 10 of the L-shaped angle 3, and the protrusion 10 , 10 and the fulcrum shaft hole 12 of the fulcrum boss 11. It is inserted and fixed with a stopper 16 to prevent the fulcrum shaft 15 from coming off.

[0011] As shown in FIGS. 3 to 6, the inside of the hole 2 of the speaker box 1 is 17 and has a bent portion 18' for guiding the movement of the L-shaped angle 3. 18 is provided, and a bulging portion 19 is provided within the end of the strip hole 2 facing the bent portion 18'. Ru.

0012 In the speaker box 1 shown above, install the L-shaped angle 3 on the wall. The fixing method will be explained below. As shown in Figure 3, speaker box 1 Insert and place the L-shaped angle 3 into the strip hole 2, then insert the screw 4 from the box hole 20. Insert the fulcrum boss screw 13 of the fulcrum boss 11 pivotally connected to the L-shaped angle 3 in the L direction. Insert it while twisting and pivot it through the other box hole 21 with the screw fastener 5.

[0013] By further twisting the screw 4 in the L direction, the protrusion 10 of the L-shaped angle 3 move in the Y direction while contacting the inner wall 18 of the box 1, and press the L-shaped angle 3. As shown in FIG. 3 moves in the Y direction while rotating in the S direction around the fulcrum shaft 15 of the fulcrum boss 11. . Furthermore, by twisting the screw 4 in the L direction, an L-shaped angle is created as shown in Figure 5. The holding part 8 of 3 comes into contact with the bulge part 19 of the strip hole 2, and the L-shaped angle 3 is pressed against the speaker box. The box 1 is housed in a space in a hole 2 provided on the side surface of the box 1.

[0014] Place the speaker box 1 in the state shown in Figure 5 above on the wall, ceiling, etc. where appropriate. Drill a hole that matches the outer shape of speaker box 1, and insert it into the rear of speaker box 1. The edge 6 is brought into contact with the wall end 22 by inserting from the side.

[0015] For example, with the speaker box 1 inserted into a hole drilled in the wall, screw the screw 4 in the R direction. By twisting the L-shaped anchor in the opposite direction to that detailed in Figures 3 to 5, The angle 3 rotates in the T direction and moves in the X direction, and the holding part 8 of the L-shaped angle 3 touches the wall surface. It abuts the end portion 22 . By twisting screw 4 more strongly in the R direction, the L-shaped angle The protrusion 10 of the L-shaped angle 3 comes into contact with the inner wall 18 or the screw 4 supports the L-shaped angle 3. The point inner wall 7' abuts, and the holding part 8 of the L-shaped angle 3 firmly holds the wall end 22. Press.

[0016] Therefore, the speaker box 1 has an edge 6 of the speaker box 1 and a plurality of L-shaped parts. The wall end portion 22 is held between the angle 3 and the device is mounted on a wall, ceiling, etc.

[0017]

[Effect of the idea]

Since the speaker box fixing device according to the present invention is in the above-mentioned condition, , There is no need to drill through holes in the ceiling etc. to fix the speaker box. Installation work can be done from the front side.
