Description

  The present invention relates to an apparatus for hanging and fixing AV equipment such as a projector from a ceiling.

  Conventionally, a projector is installed on a desk or table and projected onto a screen every time it is used. However, in order to use the room widely, it is often installed by suspending a device from the ceiling.

FIG. 7 is a perspective view of a conventional projector suspending device. In this device, a moving member 34 is rotatably mounted in a horizontal direction around a main pipe 33 that is engaged with a pipe 32 that is suspended from a ceiling via a mounting plate 30 so as to be movable up and down. The mounting base portion 36 is pivotally attached to the pivot shaft 35 so that the direction can be adjusted from the ceiling surface.

  However, in order to adjust the left-right rotation or the vertical swing, the fixing screws 39 and 41 are loosened each time, and there is a trouble of fixing after positioning. Furthermore, these adjustment parts are exposed, and there is a problem of deteriorating the beauty of the ceiling. Moreover, in the invention disclosed in Patent Document 1, six directions of adjustment are possible, but each adjustment has the trouble of loosening the fixing nut and rotating the adjustment nut.
