Description

  The present invention relates to a ceiling suspending device for a thin display used when a thin television monitor or a computer display (hereinafter referred to as a thin display) is suspended from a ceiling surface.

  Conventionally, this type of thin display suspending apparatus is often used with a structure in which a base box is attached to the lower end of a column suspended from a ceiling and the thin display is screwed to the base box. In this type of structure, the side of the column is threaded and the base box is mounted using a nut that is screwed to the screw.

On the other hand, Patent Document 1 describes a PDP mounting device devised to facilitate the mounting work of a plasma display panel (PDP) which is a kind of thin display. As an example of the mounting device, a base plate to be mounted on the ceiling, a rotating pole suspended from the base plate, a mounting bracket to be mounted on the rotating pole, and a screw threaded in a spiral groove of the rotating pole at a lower stage of the mounting bracket. An apparatus is described that includes rotating metal fittings. In order to attach the PDP to the rotating metal fitting, the rotating metal fitting and the PDP are screwed.
JP 2001-282131 A

  As described above, in the structure in which the nut is screwed to the support and the base box is mounted, since the diameter of the support is large, a large nut is required. Since such a large nut is not usually used for electric wiring equipment construction, a large nut used for plumbing such as a water pipe has been substituted. However, in order to use such a special nut, the tool for tightening this nut must also be for piping work. Also needed to carry.

  Also, piping work tools that tighten large nuts are also large in size, making them difficult to handle in wiring work where there is a lot of work in confined spaces, and may not be securely tightened. .

  In addition, since the base box and the thin display also rotate with the rotation of the large nut after mounting, there is a risk that the thin display will rotate or drop if the nut is loosened.

  Further, in the structure in which the thin display is screwed to the base box or the like attached to the support column, the screw is removed every time the thin display is attached / detached, and is screwed again when reattaching. For this reason, a lot of labor is required for attaching and detaching the thin display. Moreover, since the weight increases as the screen of the thin display becomes larger, when a large thin display is mounted, the work is performed while supporting a considerable weight, and the mounting work is extremely difficult. For this reason, the accident accompanying the fall of a large-sized thin display is also increasing.

  In addition, in the structure in which the thin display is screwed to the base box or the like attached to the support column, it is difficult to adjust the support angle of the thin display and adjust the mounting position.

  On the other hand, as in Patent Document 1, in a structure in which a mounting bracket is attached to a rotating pole and the mounting bracket is provided with the rotating bracket, the angle of the PDP can be adjusted via the rotating bracket. However, since the connection between the rotating metal fitting and the PDP still requires a screwing operation, the above-mentioned many problems such as the delay of the attaching / detaching operation accompanying the screwing operation have not been solved.

  Therefore, the present invention has been created to solve the above-mentioned problems, and it is possible to attach and detach the thin display very easily and reliably, and also to adjust the support angle of the thin display and to adjust the mounting position. An object of the present invention is to provide a ceiling display device for a thin display which can be easily performed.
