[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used for attaching to a wall surface of a flat part of a room of a speaker box for BGM or an announcement used in a place where people gather, such as a living room or a lobby, and can be attached and detached easily and freely. The present invention relates to a speaker box mounting device that can be attached and detached.

[0002]

[Prior art]

 Conventionally, this type of speaker box mounting device has a nail-like hanging metal fitting (31) having a hanging portion (metal fitting) fixed to the wall surface (11) by fastening or driving as shown in FIG. The speaker box (12) was mounted by hanging it by fitting it into the hole of the hanging bracket (32) on the speaker box side.

[0003]

[Problems to be solved by the device]

 Therefore, in the conventional suspension mounting device for this type of speaker box (12), when mounting on a flat flat wall surface (11), the suspension metal fitting (31) on the speaker box side is attached to the speaker box (12). Since it is attached to the back side, it is difficult to fit the holes of the metal fittings (32) on the speaker box side to the hanging metal fittings (31) on the wall surface (11) side.Especially in a high position, extra labor is required for mounting. However, it has a drawback that the speaker box is not stable after mounting. In addition, since the position of the hanging metal fitting (31) cannot be seen even at the time of removal, there is a drawback that it takes time to remove.

In particular, when the speaker box has a corner shape with a recessed rear surface, the speaker box has poor stability and is difficult to install and remove. In addition, in order to utilize the acoustic reflection of the wall surface, two corner speaker boxes such as this are installed side by side on flat walls so that the acoustic radiation output of each can be reduced by parallel driving. In the case of a double speaker box that emits sound evenly in every corner of the room with high efficiency and broad radiation directivity, the installation mode is unstable, and it is extremely difficult to install it especially in high places. was there. Speaking strongly, it was no exaggeration to say that there was no peaker mounting device on the market that could be easily attached to and removed from the wall.

Therefore, in order to solve the problems of such a conventional speaker box mounting device, the present invention combines the structures of the mounting brackets on both the flat wall surface side and the speaker box side. By adding a device to the structure that is easy to put on and take off, in a mode in which two sets of speaker boxes are attached back to back, it is possible to suppress the cost rise of parts and attach and detach freely and easily. An object of the present invention is to provide a speaker box mounting device that can significantly reduce and shorten the labor and time required for mounting and dismounting.

[0006]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to FIGS. 1 to 10 corresponding to the embodiments. The present invention shows that wide strip-shaped metal plates are bent at right angles to each other into an L-shape. The bent pieces (1a) and (1b) are formed by forming the stepped parts (2) and (2) on both side edges of one bent piece (1a) of the mounting bracket (1), and The insertion fitting rails (2a), (2a) are formed and mounting holes (4a), (4a), (4b), (4b) are formed inside the stepped portions (2), (2). The bent spring plate material (3) with the hook part (3a) at the tip facing outward, and the mounting part (1) that is constructed by fixing the base part (3b) to the outside. , Insert the setscrews (15), (15) through the mounting holes (4a), (4b) and tighten them on the wall surface (11) side to be mounted, and mount the other side of the mounting bracket (1). Insert the setscrews (14), (14) into the mounting holes (4c), (4d) formed on both side edges of the bent piece (1b), and Tighten it to the back (6f ') of the second speaker case body (6b) of the peaker box (10b), fix the second speaker box (10b), and attach it to one side of the first speaker case (6a). On the back surface (6f), a base (6e) is provided along the lateral direction of the formed recess (6d), and a U-shaped insertion fitting (5) is placed on it to set screws ( 16) and (16) are attached and fixed to form the receiving parts (5a) and (5a) into which the rails (2a) and (2a) of the mounting bracket (1) on the wall surface (11) side are fitted and inserted. Then, at the corresponding position of the concave portion (6d) of the first speaker case (6a) corresponding to the spring plate material (3) of the mounting metal fitting (1), the convex portion (7) engaging with the hook portion (3a) is provided. Insert the rails (2a), (2a) of the mounting bracket (1) into the receiving part (5a) formed in the speaker case (6a) of the formed first speaker box (10a). , Mounting brackets attached to the first speaker box (10a) and wall surface (11) This is a speaker box mounting device that is combined with (1).

[0007]

[Action]

 The present invention adopts the above-mentioned measures to the structure of the mounting bracket (1) and the receiving portion (5a) on both the conventional wall surface (11) side and the speaker box (10a), (10b) side to be mounted. Because of the added structure, at the time of mounting, first use the mounting holes (4c) and (4d) of the bent piece (1b) of the mounting bracket (1) to mount the mounting screws (14) and (14). To the rear (6f ') of the speaker case (6b) of the second speaker box (10b), and then attach the mounting bracket (1) using the mounting holes (4a) and (4b). Tighten to the wall surface (11) with the set screws (15) and (15) to fix it. In this way, the second speaker box (10b) is attached to the wall surface (11) by the attachment fitting (1).

Next, the insert fitting (5) is attached and fixed to the pedestal portion (6e) of the rear surface (6f) of the speaker case (6a) of the first speaker box (10a) with a set screw (16) or the like. A part (5a) is formed, and the leaf spring (3) of the bent piece (1a) attached to the wall surface (11) is fitted and inserted in the receiving part (5a) in the direction of the arrow to form the cabinet body (6a). The first speaker box is automatically operated by simply pushing it in until the hook part (3a) at the tip of the plate panel (3) of the bent piece (1a) fits into the convex part (7) formed on the first speaker box. (10a) can be firmly attached and fixed to the wall surface (11). In this way, the first speaker box (10a) and the second speaker box (10b) can be easily attached and fixed back to back on the wall surface (11).

In the case of detaching, by reverse operation, slide the first speaker box (10a) in the direction opposite to the arrow to unlock the hook portion (3a) and the convex portion (7), It can be easily separated by pulling it out.
