Embodiment Construction

[0019] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0020] figure 1 (a) in (a) is a view showing an example of a use state (a state in which the audio device is mounted on a rack) to which the audio device or the speaker set of the audio device according to the embodiment of the present invention is applied. In the present embodiment, the audio equipment is fixedly mounted to the rack 11 by a cylindrical post 12 attached to the rack 11 . Although a pair of left and right speaker devices 10 are exemplarily shown as audio devices or audio devices, the basic principles of the present invention can be applied to various other audio devices other than speakers, such as a mixer device.

[0021] The electronic keyboard instrument KB is connected to the mixer device 13 , and the speaker device 10 is also connected to the mixer device 13 . When not in use, the sound mixer device 13 can be housed in the hollow portion S1 formed ...

Abstract

The distal end of an inserted pole (12) makes contact with a taper surface (23) or bottom surface (23) of the portion corresponding to the bottom of the insertion hole (20). A lever (40) rotates about a rotating shaft (43), and a pressing surface (41a) facing from a notched part (25) formed in the insertion hole (20) presses the side part of the pole (12). The pole (12) pressed by the pressing surface (41a) is mainly received by projections (22C to 22F), particularly the projections (22D, 22E) positioned on the opposite side with a shaft center (C) therebetween in relation to the pressing surface (41a). The projections (22D, 22E) are positioned on both sides of the pole (12) with the cross section along the line A-A therebetween as viewed in the axial direction. As the lever (40) is rotatably operated in the tightening direction (F), the pressing position (P) gradually approaches the shaft center (C), thereby increasing the pressing force.

Description

technical field [0001] The present invention relates to audio equipment such as loudspeakers or audio equipment which can be fixedly mounted to a rack by being detachably attached to a post of the rack. Background technique [0002] Hitherto, there have been known audible equipment or audio equipment such as loudspeakers and mixer units fixed to posts of a rack. According to what is disclosed in Patent Document 1, for example, the bracket part is provided at the distal end of the cylindrical rack column, the two bracket screws provided on the seat of the bracket part are screwed into the audio equipment, and the bracket part is connected by the thumb screw Secured to the distal end of the post. [0003] Prior art literature: [0004] Patent Document 1: Japanese Patent No. 4496904 [0005] However, for the installation structure disclosed in Patent Document 1, it is necessary to first fix the bracket part to the column of the rack, and in addition, because the bracket part...
