Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a stand structure for a liquid crystal television.

[Conventional technology]

Conventionally, the liquid crystal televisions are mainly pocket type (hereinafter referred to as P type). There were two types of shapes, a vertically long type and a horizontally long type. The reason for this is that the liquid crystal display section cannot be overlapped with a plurality of constituent elements and the battery storage section because the thinness is strongly required for the portable orientation, and the plane aspect ratio must be increased. Further, in consideration of an efficient layout, it was necessary to make it rectangular in plan view. Currently, space-savings such as miniaturization and integration of internal constituent elements and high-density mounting are being achieved, but the miniaturization has not been achieved sufficiently.

However, in recent years, the needs of a desktop type (hereinafter referred to as DT type), which should be called a small type of so-called home CRT image receiving device, in which the plane aspect ratio is prioritized (small) (the display portion ratio is large) and the thickness is increased, are intended and used. Both types have been developed by the respective companies because the locations and the like are increasing.

The above-mentioned stand structure used in the liquid crystal television is a P-type slab-shaped plastic or wire material, and has a rotary shaft at one end and the rotary shaft is rotatably embedded in the main body, and a stopper is provided near the rotary shaft. Is provided and functions by opening and closing the range. For the DT type, a table with an angle is directly attached to the lower surface of the main body, etc., or it is fixed to a special stand with screws or the tilt angle of the main body is increased. By doing so, some of them used the above type of stand.

That is, the great difference between the P type and the DT type is in the center of gravity position, and since the P type is thin as seen from the viewer side, the center of gravity position is in the backward direction, whereas the DT type is in the front direction because it is thick. Therefore, the structure of the stand is determined by the position of the center of gravity, and it is necessary to provide a unique stand for each.

Further, since liquid crystal televisions have a problem that the viewing angle is limited, both types were required to have a variable angle as a stand function, but the structure was complicated and the cost was increased. There was only a few.

[Problems to be solved by the device]

Conventionally, it was necessary to separately provide a stand for both types, increasing the initial cost and increasing the development cost, and in order to satisfy the requirements for the angle variable function, the assembly becomes complicated and the durability is reduced and the cost is reduced. There were many problems such as being up.

Then, this invention aims at solving the problem of a prior art.

[Means for Solving the Problems]

In order to achieve the above object, the liquid crystal television stand of the present invention comprises a main body fixing portion, an intermediate beam portion and a base fixing portion which are flexibly connected by plastic integral molding, and a supporting plate is bendably provided on the intermediate beam portion. In addition, the main body fixing slit and the supporting plate slit are provided in the base fixing portion, and different fixing means can be supported depending on whether the front surface or the back surface of the base fixing portion is selected as the ground plane. By arranging a plurality of slits in the base fixing portion, a fixed angle changing function is provided.

[Action]

When the main body fixing part of the stand is attached to the existing mounting part on the rear surface of the liquid crystal television main body and the arbitrary fixing means is set, the base fixing part is arranged on the rear side when the center of gravity is on the projection surface on the rear side of the main body. The support plate in the intermediate beam portion is pulled out, and the hook-shaped tip is inserted and fixed in the slit in the base fixing portion. The center of gravity moves by moving the rod antenna, but it does not fall down because it is inside the base fixing part. When the center of gravity comes to the projection surface on the lower surface of the main body, the base fixing portion is inverted and fixed by inserting a hook or the like existing on the lower surface of the main body into another slit provided in the base fixing portion. With respect to the movement of the center of gravity, the base fixing portion is arranged in the range of movement of the center of gravity as described above, so that it does not fall.

When the angle is variable, the angle of the main body can be changed on the principle that the ratio of the internal angles changes when the length of the base of the triangle is changed by moving a plurality of slits provided in the base fixing part.

〔Example〕

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view of a stand of the present invention, in which 1 is a main body fixing portion, 2 is an intermediate beam portion, and 3 is a base fixing portion, which are connected via hinges 1b and 2d, respectively. Base fixing part 3
Since it is bendable, it can be folded when it is stored, and it encloses the intermediate beam part 2 and has two sets of base fixing hooks 2c and 3c.
It is stored and fixed at. It will be described below in use.

FIGS. 2 and 3 show an embodiment of the present invention, and FIG. 2 shows a P-type liquid crystal television (relatively thin, in which the moving range of the center of gravity 6 is on the rear projection surface) in use. . The stand has a main body fixing hook 1a of the main body fixing portion 1 and an intermediate beam portion 2 at a position where the fulcrum 4a of the main body 4 substantially contacts the back surface of the main body 4.
It is fixed to the main body by fixing means such as the main body fixing auxiliary hook 2e. The support plate 2a is provided to the intermediate beam portion 2 so as to be bendable, and when used, the support plate hook 2b provided at the leading end of the intermediate beam portion 2 is inserted into and fixed to the support plate slit 3b provided in the base fixing portion 3. . The angle can be adjusted by changing the positions of a plurality of supporting plate slits 3b, as shown by the chain double-dashed line. At that time, the range of movement of the center of gravity is set to be within the base fixing portion 3. Further, the barycentric position is set to be within the base fixing portion 3 at any position when the rod antenna 4b is fully extended.

FIG. 3 shows a DT type liquid crystal television (relatively thick, center of gravity 7
(The moving range is on the lower surface side projection surface of the main body and the rear surface side projection surface of the main body) are in use, and the same stand of the present invention is used to set the main body 5 as shown in the figure and the base fixing portion 3 is hinged 2d. The main body hook provided on the main body 5 is inverted and inserted into and fixed to the main body fixing slit 3a of the base fixing portion 3. The angle adjustment is the same as described above. Further, the movement of the center of gravity by the rod antenna 5b is also the same as described above.

In addition, when supporting the DT type, the unnecessary supporting plate 2a is housed in the intermediate beam portion 2.

[Effect of device]

As described above, according to the present invention, by using both types of stands, not only the initial cost is greatly reduced but also the cost of parts is reduced due to the effect of mass production. In addition, the angle variable function is realized with a simple structure with the minimum number of parts. Furthermore, it is possible to realize a product with excellent cost performance that is excellent in durability, assembling, and has high reliability.
