Description

  The present invention relates to a television receiver set including a television receiver and an indoor antenna, and is particularly preferably applied to a television receiver set that receives terrestrial digital broadcasting and the like, and adjusts an installation angle of a video display unit. The present invention relates to a television receiver set in which the direction of the antenna does not change even if it is performed, and the direction of the antenna does not need to be adjusted.

Conventionally, the antenna mounted on the television receiver is generally attached directly to the receiver housing, and when the user changes the installation angle so that the video display unit is easy to see, the orientation of the antenna also changes at the same time. The reception status was affected.
This is because the antenna mounting part and the video display unit of the television receiver are directly coupled to each other, and after changing the installation angle of the video display unit, it is necessary to return the antenna to the original direction. For example, Patent Document 1 discloses a structure in which an indoor antenna is attached to a television receiver, or a structure in which the indoor antenna is installed on a top surface of a television receiver housing with a desktop structure.
Further, Patent Document 2 proposes to attach an antenna to a communication device casing, but this is intended for an antenna storage method, and is intended to prevent screen angle adjustment and antenna setting angle from being influenced by each other. It is different from the invention.

  Terrestrial digital broadcasting has a characteristic that the reception state is greatly affected by the installation position of the antenna even indoors. For this reason, there is a demand to fix the orientation of the indoor antenna at a position where the reception state is optimal. On the other hand, there is a demand for the user to point the screen of the television receiver in an easy-to-see direction according to his / her position. For this reason, in the conventional method of installing an indoor antenna, that is, the method of installing the indoor antenna on the top surface of the television receiver housing or the like, if the orientation of the television receiver is changed, the orientation of the antenna changes accordingly. Therefore, there is a problem that the reception sensitivity of the television signal is also affected.

  By the way, it is considered that the structure in which the conventional indoor antenna is installed on the top surface of the television receiver housing is caused by the box shape of the television receiver housing. The television stand has a box shape like the television receiver housing in order to place the box television receiver housing.

  On the other hand, in recent years, so-called flat panel displays (hereinafter referred to as FPD) using liquid crystal technology or plasma technology have been put into practical use. A television receiver employing such an FPD is changed from a conventional box shape to a thin plate shape, and the shape of a television stand that supports the television receiver has changed from the conventional box shape to a stand shape.

For this reason, in a television receiver employing FPD, it is not preferable that the indoor antenna is installed on the top surface of the television receiver housing as in the prior art.
In view of the change in the shape of the television receiver as described above, and the change in the shape of the television stand that accompanies the change, there is a problem in that it is not desired to change the orientation of the antenna even if the orientation of the television receiver is changed. The structure of the television receiver set for solving is proposed.

In order to solve the above problems, the present invention has taken the following measures.
That is, the invention according to claim 1 is a television receiver set having an antenna and a video display unit, wherein a structure with a joint mechanism capable of changing the orientation of the video display unit between the video display unit and the antenna is provided. The antenna is attached to the structure with a joint mechanism, and the installation angle of the antenna is not changed even if the installation angle of the video display unit is changed.

  The invention according to claim 2 is a television receiver set comprising a television receiver, a television stand, and an antenna, wherein the television stand has a joint mechanism for locking the television receiver, The television receiver is installed on the television stand, and an installation angle of the television receiver can be adjusted via the joint mechanism.

  According to a third aspect of the present invention, in the television receiver set according to the second aspect, the television receiver is a television receiver using a flat panel display, and the television base includes a pedestal and a column, The antenna is attached to the support column.

In the method of installing the indoor antenna on the top surface of the television receiver housing as in the conventional method of installing the indoor antenna, when the installation angle of the television receiver housing is changed, the indoor antenna is Since the installation angle of the antenna was also changed, the antenna orientation had to be readjusted after changing the installation angle of the television receiver housing.
According to the present invention, in a receiver with a relatively light image display unit such as a liquid crystal television, even if the installation angle is changed to an angle at which the user can easily view the video display unit, the installation angle of the antenna is mechanically affected. It is excellent in installation adjustment and can always maintain the best reception state.

  The present invention provides a television receiver set including an antenna and a video display unit, wherein a structure with a joint mechanism capable of changing the orientation of the video display unit is interposed between the video display unit and the antenna, Mounting on the non-moving side of the joint mechanism, even if the installation angle of the video display unit is changed, the installation angle of the antenna is not changed, and this allows the video display unit and the antenna to be adjusted independently. In this way, it is coupled to a stand or a wall-hanging angle which is a structure with a joint mechanism such as a movable joint. On top of that, even if the angle of the image display unit is changed, the structure such as a stand or wall hanging angle which is an intermediate frame is fixed to the desktop or wall surface (it may not be completely fixed) The antenna orientation does not change.

With regard to the structure of the television receiver set according to the present invention, an embodiment using a liquid crystal television when the flat panel display (FPD) is a liquid crystal display (LCD) will be described below.
