Description

  The present invention relates to a hanging device for a video display device capable of hanging and supporting a thin display such as a plasma display or a liquid crystal display from a ceiling.

Various devices have already been proposed as suspension devices for suspending the video display device from the ceiling. For example, a threaded portion is formed at the lower end of a cylindrical suspension member, and a through-hole formed in the top plate portion of the gate-shaped mounting bracket is inserted into the threaded portion, and protruded from the lower end of the mounting bracket. The mounting bracket is fixed to the suspension member by screwing the nut to the threaded portion of the suspension member, and the cylindrical bracket with the guide pins standing upright on the outer surfaces of the left and right vertical wall portions of the installation bracket is provided. A substantially arc-shaped locking member projecting outwardly on the left and right sides, rotatably supported by the pair of left and right cylindrical metal fittings, and having a long hole that engages with the guide pin is provided on the back surface of the video display device. It is fixed. Therefore, installation brackets with cylindrical fittings at both left and right ends are installed on a suspension member fixed to the ceiling, and a pair of left and right attachments attached to the cylindrical fittings of the installation fitting of the suspension member, for example, on the back surface of the plasma display. The angle of the plasma display is set after the stop member is placed on a pair of left and right cylindrical fittings to support the weight of the plasma display (see, for example, Patent Document 1).
