Description

  The present invention relates to a television board for installing a flat-screen television such as a liquid crystal television or a plasma television.

  Conventionally, when a flat-screen television such as a liquid crystal television or a plasma television is installed in a living room, there is a rack-type television board (see, for example, Patent Document 1). This type of TV board can be used simply by placing a flat-screen TV on the top surface of the TV board, and AV equipment such as a DVD recorder and HD recorder can be stored in a shelf provided inside the TV board. It is good. On the other hand, there has been proposed one in which a thin television is attached to a movable member such as a rotating arm, and the orientation of the television screen can be freely changed to some extent as necessary (see, for example, Patent Document 2).

JP 2004-153771 A JP 2007-209622 A

  The “AV system rack” described in Patent Document 1 is easy to use because it can be used simply by placing a flat-screen TV. However, if you want to change the orientation of the TV screen, you can rotate the dedicated stand attached to the flat-screen TV. It can be handled only within the range of the moving / tilting function. For this reason, the orientation of the television screen may not be set to a state according to room conditions or viewer preference.

  On the other hand, the “storage shelf equipped with a TV mounting device” described in Patent Document 2 can be mounted on a TV relatively freely within the range of the rotation / tilting function of the TV mounting device because a flat-screen TV can be mounted without using a dedicated stand. The screen orientation can be changed. However, since this television mounting apparatus is a system in which a thin television is suspended and held near the tip of the rotating arm, a heavy thin television cannot be attached due to its structure. For this reason, it is difficult to cope with the recent increase in screen size.

  The problem to be solved by the present invention is to provide a television board in which a relatively large thin television can be installed in a stable state and the orientation of the television screen can be changed over a wide range.

The television board of the present invention includes a substantially box-shaped rack portion placed on a predetermined installation surface, a panel portion erected on the rack portion, and from the bottom surface of the rack portion along the back surface of the panel portion. A metal support frame disposed on the display unit, and a TV holding unit connected to the support frame through an opening formed in the panel unit for attaching a thin TV.
The support frame and the television holding unit are connected by using at least a pair of hinge members arranged opposite to each other with the rotation axis vertical and a vertical support shaft that rotatably holds the blades of the hinge members. Features.

  With such a configuration, the TV holding unit to which the thin TV is attached is connected to a metal support frame disposed along the back surface of the panel unit from the bottom surface of the rack unit. A large thin TV can be installed in a stable state. In addition, the support frame and the television holding portion are connected by a vertical support shaft that rotatably holds at least a pair of hinge members that are opposed to each other with the rotation axis vertical, and the blades of the respective hinge members. Since the holding unit can rotate in the left-right direction and can move back and forth in the front-rear direction, the orientation of the TV screen attached to the TV holding unit can be changed in a wide range.

  Here, in order to detachably attach the flat-screen television to the television holding portion, a mount member attached to the back surface of the thin-screen television, and a tilting mechanism for holding the mount member tiltable in the front-rear direction with respect to the television holding portion Since the flat-screen television can be tilted in the front-rear direction, the range of changing the orientation of the television screen can be expanded.

  In this case, as the tilting mechanism, the television holding part is provided with at least a pair of locking members arranged horizontally and in parallel in the vertical direction, and the mount member can be rotated to one of the locking members. If the hook part latched by this and the adjustment part latched by the other said locking member so that a movement to the front-back direction is provided, the inclination state of a television screen can be changed easily.

  According to the present invention, it is possible to provide a television board in which a relatively large thin television can be installed in a stable state and the orientation of the television screen can be changed in a wide range.
