[0011] The speaker support according to the present invention will be described in detail below with reference to the drawings. The embodiment described below is a preferred example for carrying out the present invention, and therefore various technical limitations are imposed. However, the present invention is not limited to this embodiment unless otherwise specified in the following description.

[0012] A speaker support according to an embodiment of the present invention will be described with reference to Figures 1 to 3. Figure 1 is an external perspective view showing the speaker support according to an embodiment of the present invention. Figure 2 is an exploded perspective view of the speaker support according to the embodiment. Figure 3(a) is a top view of a ceiling mounting member according to the embodiment. Figure 3(b) is a front view of the ceiling mounting member according to the embodiment. Figure 3(c) is a side view of the ceiling mounting member according to the embodiment.

[0013] As shown in FIGS. 1 and 2, the speaker support of the embodiment comprises a speaker mounting member 10, a ceiling mounting member 20, and a connecting portion 30, and is used to mount a speaker on a ceiling so as to hang it from the ceiling.

[0014] The speaker mounting member 10 has a wire connection portion 11 and a plurality of first screw insertion holes 12, and is attached to a speaker 1 (see FIG. 6). One end 51 of a locking wire 50 that locks the speaker mounting member 10 to a ceiling is connected to the wire connection portion 11. The other end 52 of the locking wire 50 is fastened to, for example, a ceiling material 2 (see FIG. 6) with a screw. Screws for fixing the speaker 1 to the speaker mounting member 10 are inserted into the plurality of first screw insertion holes 12.

[0015] 3, the ceiling mounting member 20 is attached to a ceiling and includes a pair of ceiling mounting plates 21 to be attached to the ceiling and a groove portion 22 having a U-shaped cross section. The pair of ceiling mounting plates 21 have a plurality of second screw insertion holes 21a. Screws for fixing the ceiling mounting member 20 to the ceiling are inserted into the plurality of second screw insertion holes 21a.

[0016] The groove-shaped portion 22 of the ceiling mounting member 20 is disposed between the pair of ceiling attachment plates 21 and has a first bottom plate portion 22a and a pair of first side plate portions 22b. The first bottom plate portion 22a has equal-width notches 22c extending in the longitudinal direction of the groove-shaped portion 22. The pair of first side plate portions 22b are connected to the pair of ceiling attachment plates 21 at their upper ends.

[0017] The equal-width notch 22c extends from one end of the groove-shaped portion 22 in the longitudinal direction to the circular notch 22d. The circular notch 22d has a diameter larger than the width of the equal-width notch 22c, and is formed at the middle position of the groove-shaped portion 22 in the longitudinal direction.

[0018] The connecting portion 30 connects the speaker mounting member 10 to the ceiling mounting member 20 so as to be rotatable in at least one axial direction. As shown in Fig. 1 , the connecting portion 30 is connected to the speaker mounting member 10 so as to be rotatable around a rotation axis 30a supported by the speaker mounting member 10. The connecting portion 30 also has an arc-shaped notch 30b formed so as to penetrate the connecting portion 30, for example, in the thickness direction, and a plurality of engagement recesses 30c formed on the inner diameter side of the arc-shaped notch 30b so as to be aligned in the circumferential direction of the arc-shaped notch 30b.

[0019] Meanwhile, a rotation-preventing screw 30d is attached to the speaker mounting member 10 so as to be movable in the radial direction of rotation but not in the rotation direction. The rotation-preventing screw 30d is inserted through the arc-shaped notch 30b, and by tightening the rotation-preventing screw 30d while engaged with one of the plurality of engagement recesses 30c, the connecting part 30 is fixed to the speaker mounting member 10 at any angle within the range of the arc-shaped notch 30b.

[0020] The connecting portion 30 also includes a profile 31. The profile 31 has a U-shaped cross section, a second bottom plate portion 31a, and a pair of second side plate portions 31b, and is fitted into the interior of the groove-shaped portion 22 so as to be in sliding contact with the first bottom plate portion 22a and the pair of first side plate portions 22b of the groove-shaped portion 22. The weight of the speaker 1 attached to the speaker mounting member 10 is supported by the first bottom plate portion 22a of the groove-shaped portion 22 abutting against the second bottom plate portion 31a of the profile 31 from below.

[0021] The connecting portion 30 will be described in more detail below with reference to Figures 4 and 5. Figure 4(a) is a front view of a speaker support in an embodiment in which a ceiling mounting member is fixed to the connecting portion. Figure 4(b) is a front view of a speaker support in an embodiment in which the ceiling mounting member has been removed from the connecting portion. Figure 5 is a vertical cross-sectional view of the first bottom plate portion in an embodiment in which a circular plate is fitted into a circular notch.

[0022] 4 and 5, the connecting portion 30 has a circular plate 32. The circular plate 32 is provided so as to come into contact with the second bottom plate portion 31a of the section 31, and fits into the circular notch 22d when the section 31 is fitted inside the groove-shaped portion 22. The circular plate 32 is installed between the main body portion of the connecting portion 30 having the arc-shaped notch 30b and the second bottom plate portion 31a of the section 31.

[0023] A circular spacer 33 is disposed between the main body of the connecting portion 30 and the circular plate 32, and the shaped member 31, circular plate 32, and circular spacer 33 are fixed to the main body of the connecting portion 30 with mounting bolts 34 and nuts 35. The diameter of the circular spacer 33 is smaller than the width of the equal-width notch 22c, and when the shaped member 31 is fitted into the groove-shaped portion 22 with the speaker 1 attached to the speaker mounting member 10, the shaped member 31 is fitted into the groove-shaped portion 22 by sliding it horizontally to a predetermined position with the circular spacer 33 positioned inside the equal-width notch 22c and the circular plate 32 positioned inside the groove-shaped portion 22.

[0024] When the section 31 moves to a predetermined position, as shown in FIG. 5, the circular plate 32 fits into the circular notch 22d, and the section 31 is temporarily fixed so as not to move in the horizontal direction.

[0025] The speaker support of the embodiment further includes a shaft insertion hole 40. A shaft-shaped fastening member 41 is inserted through the shaft insertion hole 40, and the shaft insertion hole 40 is formed so as to penetrate through at least one of the pair of first side plate portions 22b and at least one of the pair of second side plate portions 31b.

[0026] In the embodiment, a first through hole 22e and a second through hole 31c serving as shaft insertion holes 40 are formed in the pair of first side plate portions 22b and the pair of second side plate portions 31b, respectively. In the embodiment, a female thread is formed in the second through hole 31c, and a fastening member 41 is screwed into the female thread of the second through hole 31c, thereby fixing the section 31 to the groove-shaped portion 22.

[0027] Figure 6 shows the final state in which the speaker 1 is attached to the ceiling material 2 using the speaker support of the embodiment. In the final state shown in Figure 6, the speaker mounting member 10 is fastened to the ceiling material 2 by the fastening wire 50. Therefore, even if a screw fastening the speaker support to the ceiling material 2 falls out, the speaker will not immediately fall from the ceiling, ensuring time for a user who notices the problem to take appropriate measures.

[0028] 1 to 6, according to the speaker support of the embodiment, when attaching speaker 1 to the ceiling, circular plate 32 of connecting part 30 fits into circular cutout 22d of ceiling mounting member 20, temporarily securing connecting part 30 so that it does not come off ceiling mounting member 20. Therefore, until connecting part 30 is fixed to ceiling mounting member 20 with fastening member 41, there is no need to support the weight of speaker 1 with one hand, and the speaker can be safely attached to the ceiling by one person.

[0029] Furthermore, with the speaker support of the embodiment, a fastening member 41 is inserted into a shaft insertion hole 40 formed to penetrate at least one of the pair of first side plate portions 22b and at least one of the pair of second side plate portions 31b, and the connecting portion 30 is fixed to the ceiling mounting member 20. If the shaft insertion hole 40 is formed to penetrate, for example, the first bottom plate portion 22a of the groove-shaped portion 22 and the second bottom plate portion 31a of the extrusion 31, it will not be possible to tighten the fastening member 41 from the side using an ordinary long-handled screwdriver, as is clear from Figure 6.

[0030] Therefore, it is necessary to employ special fastening members 41 that can be tightened using fasteners that are difficult to operate, such as an L-shaped hex wrench, which reduces speaker mountability. However, with the speaker support of the embodiment, fastening members 41 can be tightened from the side using a regular screwdriver with a long handle, and regular Phillips or flathead screws can be used as fastening members 41, improving speaker mountability.

[0031] The embodiments of the present invention have been described above with reference to the drawings (Figs. 1 to 6). However, the present invention is not limited to the above embodiments and can be embodied in various forms without departing from the spirit and scope of the present invention.
