Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thin display device and a wall surface mounting device for mounting the thin display device on a wall surface, and in particular, the wall surface mounting function has a simple configuration and a simple operation, and the orientation of the display screen can be easily viewed by the user. Can be adjusted.

  Recently, thin display devices such as a liquid crystal television with a liquid crystal display and a plasma television with a plasma display have been developed. In such a thin display device, since the main body case is generally flat, it does not have self-supporting properties. For this reason, for example, there are those in which support legs are provided on the back surface of the main body case, and those in which the entire apparatus is thin and can be attached to the wall surface. When mounting on a wall surface, it can be considered that it is usually mounted at a slightly higher position than when it is placed on a television set. Therefore, when attaching to a wall surface, it is desired that the orientation of the display screen can be adjusted to an angle that is easy for the user to see.

Conventionally, for example, in order to adjust the orientation of the display screen, a large number of holes are arranged at fixed intervals in a fixed plate to form a positioning portion, and a protrusion of a rotating member is fitted to this positioning portion. (For example, see Patent Document 1). In addition, there are a plurality of mounting holes arranged at regular intervals on a holding plate that rotates together with the display unit, and two pins are fitted into the fitting grooves of the side frame in the mounting holes ( For example, see Patent Document 2).

  However, in the configuration described in Patent Document 1 described above, since one protrusion is fitted into one hole of the positioning portion, the size of the protrusion is reduced in consideration of stability at a predetermined angle. It is necessary to increase a certain amount or more. If it is increased, the operability at the time of angle adjustment is deteriorated. On the other hand, if the size of the protrusion is reduced, the stability at a predetermined angle is deteriorated. In the end, such a configuration can cope with a small display, but it is extremely difficult to attach the thin display device to the wall surface so that the angle can be adjusted.

  In the configuration described in Patent Document 2, two pins are required, and it is necessary to insert and remove the pins in a narrow space between the thin display device and the wall surface. In addition to being difficult to perform, there are problems such as the risk of pins coming off easily due to vibrations and the like.

Yes. The locking hole 56 is formed in such a size that a plurality of protrusions 64 to be described later can be disposed simultaneously, that is, in a long shape in the moving direction Y.

Further, as shown in FIGS. 9 to 11, the movable hinge 6 includes, for example, a sliding surface 61 that faces the holder surfaces 52 a and 52 b and a mounting portion 62 that mounts the mounting member 8. The sliding surface 61 is formed with a shaft through hole 63 through which the rotating shaft 7 passes at a position corresponding to the shaft hole 54 and a plurality of protrusions 64 in a fan shape so as to engage with the locking hole 55. Yes. At least a plurality of the protrusions 64 are formed so as to be individually disposed in the locking holes 55 other than the locking hole 56 on the outermost periphery. The protrusion 64 is formed in a long shape that engages with the long locking hole 55 described above, for example. Thus, when the shape of the protrusion 64 is formed into a long shape that engages with the locking hole 55, the contact area between the locking hole 55 and the protrusion 64 can be increased. As a result, it is possible to maintain a more stable state at a predetermined angle without particularly increasing the height t (see FIG. 11) of the protrusion 64, which is convenient.

  Since the mounting member 8 is slidably mounted on the rod-shaped support leg main body 43, when the display device main body 10 attached to the movable hinge 6 is adjusted to a desired angle, the display device main body 10 is moved upward. Since the adjustment work can be performed in the state of being slid, the adjustment work is easy to perform.

  Further, the locking hole 55 is formed in a long shape that is long in the direction orthogonal to the moving direction Y of the movable hinge 6, and the shape of the protrusion 64 is formed in a long shape that engages with the long locking hole 55. Thus, the contact area between the locking hole 55 and the protrusion 64 can be further increased. Therefore, it is possible to maintain a more stable state at a predetermined angle without particularly increasing the size of the protrusion 64 in the height direction, which is convenient.
