Description

  The present invention relates to a wall hanging device used for mounting a thin television such as a thin plasma display (PDP) or a liquid crystal display (LCD) on a wall surface.

  In recent years, flat-screen TVs such as PDPs and LCDs are becoming widespread, but when looking at the Japanese housing situation such as condominiums and detached houses, the floor space of the room is smaller than in the past, so a dedicated stand was used. TV installation on the floor tends to narrow the narrow floor space.

  Therefore, various wall-hanging devices for mounting on the wall surface of a living room / dining room or the like have been developed by taking advantage of features such as the light weight and the flat form (flat shape) of thin televisions that are becoming widespread (for example, Patent Documents). 1).

  By the way, considering the diversification of lifestyles in recent years, it is different for each living scene such as relaxing on the sofa by individuals or surrounding the table with several people. In addition, the weight of the television itself must be taken into consideration so that the wall-hanging posture against shaking caused by an earthquake or the like can be maintained.

However, the tilt angle change and maintenance of the TV wall hanging position by the conventional device can be changed and tilted with the pivot of the lower part of the TV relative to the lower pipe of the plate-like fixed base attached to the wall and the pivot point as a fulcrum (tilt adjustment) It is by stretching a string-like member composed of a chain or the like that is supported freely. That is, since it is close to a wall-hanging structure that is generally used when attaching a frame or the like to a wall surface or the like, it has not necessarily been safe against shaking such as an earthquake.
Japanese Patent Laid-Open No. 10-174021

The problem to be solved by the present invention is to provide a wall-mounted device that is highly safe against shaking such as an earthquake and that can be installed on a wall regardless of the manufacturer or size (size) of a flat-screen TV. There is.
