BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stand structure of a portable liquid crystal television.

[0002]

2. Description of the Related Art Conventionally, as a stand structure of a portable liquid crystal television, for example, a flat plate stand made of plastic or the like is disposed on the back side of the portable liquid crystal television, and a stand bearing provided on the back side is provided. The stand-shaped rotating shafts provided on both ends of the stand are mounted so that the stand is rotatable, and the stand is fixed by providing a rotation stopper on the back of the portable liquid crystal television so that the installation angle can be set. There were many things. As another example, a flat stand made of plastic or the like is replaced with a wire as a means of reducing costs. In addition, because there is no space inside the case due to the commercial nature of the light and thin design, the stand protrudes to the rear side, which impairs the external appearance or hinders the carrying.

[0003]

[Problems to be Solved by the Invention] However, in the conventional liquid crystal television, the angle of installation of the liquid crystal television can be set at only one place in the conventional system, and it has to be readjusted due to the viewing angle characteristics of the liquid crystal. The reality is that the viewer is not watching the video, or the viewer is watching the video in a posture that matches the installation angle of the liquid crystal television. For this reason, in some cases, such as a liquid crystal television with an inappropriate installation angle, the user stands on a book or the like without using the stand provided. There is a growing demand for private LCD TVs and other private products to be able to freely adjust the installation angle of the LCD TV to the viewer's attitude so that they can watch the TV in a relaxed mood.

[0004] In addition, the stand of the time for non-use by the space to fix the stand is no longer as important to miniaturization and portability is proceed as portable LCD TV and a major obstacle even on the design in order to protrude from the main body Become.
In addition, there is a demand that it is obstructive to hold the main body depending on a place where the main body is arranged, and that it is desired to be externally integrated with the main body so that it can be stored when not used. Furthermore, the poorness of the stand structure has been pointed out. This is because the stand itself is made of a plastic flat plate or wire rod, and the stand or the stand fixing part is often damaged when things are put on it or it is stepped on with the foot, so there is a need for improvement. was there. The purpose of the present invention is to make it possible to adjust the installation angle of a portable liquid crystal television, etc., to be able to respond to any posture of the viewer, and to be able to be used in any way without being damaged, and to further improve the appearance. It is an object of the present invention to provide a portable liquid crystal television stand structure in which portability is improved without deteriorating the performance.

[0005]

In order to achieve the above object, the present invention is directed to a portable liquid crystal television having a stand on the back of a main body, wherein the stand has at least one notch for preventing rotation. A rotating shaft having a rotating shaft, a friction torque generating mechanism incorporated in the rotating shaft, and a bearing portion for receiving both ends of the rotating shaft of the stand on a back surface of the main body; And a hook member having a spring property provided in the guide portion, and the stand is inserted along the guide portion provided on the back surface of the main body, and the stand is provided with a hook member. The stand is pivotally pinched by being mounted on the bearing part over the
Further, a convex shape is formed on the back side of the main body for grip, and a bearing portion capable of accommodating at least the stand is provided in the convex shape portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a portable liquid crystal television according to one embodiment of the present invention, FIG. 2 is a front view of the portable liquid crystal television of one embodiment of the present invention, and FIG. 3 is one embodiment of the present invention. FIG. 4 is a top view of the portable liquid crystal television, FIG. 4 is a rear perspective view of the portable liquid crystal television according to one embodiment of the present invention in a stand-use state, and FIG. 5 is a stand mounting part of one embodiment of the present invention. FIG. 6 is a rear view of a portable liquid crystal television according to an embodiment of the present invention, with the stand removed. FIG. 7 shows a stand according to one embodiment of the present invention, a back view, and FIG.
FIG. 3 is a cross-sectional view showing a manner of attaching (assembling) the stand according to one embodiment of the present invention.

[0007] 1 is a main body of a portable liquid crystal television, 2 is a rear surface of the main body constituting the main body, and 3 is a stand. By rotating the stand 3 in the direction of arrow A as shown in FIG.
The viewing angle can be changed. The stand 3 is constituted by inserting a torque hinge block 4 into a stand body 3a as shown in FIG. 7, and the torque hinge block 4 is constituted by a rotating shaft 4a, a friction plate 4b, a spring 4c and the like. The frictional force is generated between the rotating shaft 4a and the friction plate 4b by the compressive force of the spring 4c. A notch for preventing rotation is provided at one end of the rotating shaft 4a. As shown in FIG. 8, the stand 3 is inserted with the rotating shaft (notched portion) 4a and the rotating shaft at one end into two guide portions 2c provided on the grip portion 2a of the main body back surface 2 and pushed in the direction of arrow B. A hook member 2d having a spring property provided on the main body is provided on the way, and the hook member 2d is pushed down to the lower side (arrow C) and pushed over to the stopper portion 2e to be set on the bearing portion 2b. (FIG. 5) Also, when the stand 3 is opened because the cutout portion of the rotating shaft 4a is fitted in the bearing portion 2b on the main body side, only the friction plate is interlocked, and a rotating torque is generated. On the other hand, if the stand 3 is to be opened at a certain angle or more and a load is applied by a certain torque, as shown in FIG.
A force is applied in the direction, and the friction plate 4b of the torque hinge block 4 inserted therein pushes down the hook member 2d formed in the body for preventing the coming off, and both ends of the rotary shaft 4a are also moved from the bearing 2b on the body side. It is set so as to slide on a slope provided so as to be easily inserted into and removed from the guide portion 2c, and to come off.

[0008]

[Effect of the invention] As described above, according to the invention,
The stand can be set by simply pushing it in along the guide on the back of the main unit, so there is no need to use any fixing means such as studs on the main unit, and it is extremely easy to assemble. Because it is configured to be rotatable using the friction torque generated in the main body, the installation angle of the main body can be freely set. In addition, a locally thick grip section is provided on the back side of the main body, and the stand of the present invention is arranged in this space, so that the internal space is effectively used and easy to hold (portability), and stored without impairing the appearance. Because it is, it is excellent in design. The grip on the back side of the main body is formed in a curved shape, so the stand has a curved cross-sectional shape, so it can be thicker than conventional flat stands and has a higher cross-sectional modulus, so it is rigid. Can be improved and become very strong. Also, if the stand is stepped on during use or an abnormal load is applied to the stand, the stand gets over the hook member of the main body, so that the risk of breakage can be avoided.
