Description

  The present invention relates to a stand that supports a thin display device such as a liquid crystal display device.

  In general, a thin display device such as a liquid crystal television is provided with a supporting stand. For example, a stand shown in Patent Document 1 is fastened to a thin display device.

Utility Model Registration No. 3092539

  Usually, such a fastening operation is very troublesome and cannot be borne by the user. Therefore, it is desirable to assemble a thin display device and a stand in advance before packing. However, when assembled in this manner, the packaging size of the thin display device increases. This leads to an increase in the cost of the packaging box.

  In addition, if the packaging box becomes large, it cannot be loaded in a large amount in a container or the like. Therefore, the transportation cost also increases. Such an increase in cost may be reflected in the price of the thin display device.

  The present invention has been made in view of the above situation. An object of the present invention is to provide a stand for a thin display device and the like required for realizing the downsizing of the packing box.

  The present invention is a thin display device stand including a cover portion that protects a support portion that supports the thin display device by being connected to the thin display device, and a pedestal portion that can be attached to and detached from the cover portion.

  In such a thin display device stand, the cover portion protrudes from the outer wall of the cover portion and the hem of the outer wall away from the base of the first protrusion plate, and is covered by the first protrusion plate. A second projecting plate having a plate opening.

  Further, the pedestal portion includes a first opening that is wider than the periphery of the outer wall including the two projecting plates, an open space that serves as a space for rotating the cover that fits in the first opening, and a rotating cover. And an inner edge piece that is an edge of the open space portion that fits into the gap between the first projecting plate and the second projecting plate.

  The first protrusion plate has a first protrusion formed on one surface facing the opening of the second protrusion plate, and the inner edge piece has a first protrusion on the surface facing the first protrusion plate. It is desirable that the groove to be fitted is formed.

  Moreover, it is desirable that the first protrusion is tapered toward the tip. For example, the first protrusion is a first protrusion that is the side surface of the first protrusion by narrowing the area of the tip surface of the first protrusion that is the surface of the first protrusion, rather than the first protrusion root surface that is the surface of the first protrusion. The taper shape which inclined the side surface may be sufficient (It is still more desirable that the 1st protrusion side surface is a plane or a curved surface).

  As yet another example, the first protrusion may be tapered by including a curved surface on the surface of its own tip.

  In addition, when the cover portion fits in the first opening, it is desirable that the portion of the second protruding plate closest to the inner edge piece at the outer edge is tapered. It is more desirable that the outer edge portion of the tapered second protruding plate includes a flat surface or a curved surface.

  Moreover, it is desirable that a second protrusion that fits into the opening of the second protruding plate is formed on one surface of the inner edge piece that faces the second protruding plate.

  Moreover, it is desirable that the second protrusion is tapered toward the tip. For example, the second protrusion is a second protrusion that is the side surface of the second protrusion by narrowing the area of the tip surface of the second protrusion that is the surface of the tip of the second protrusion from the root surface of the second protrusion that is the base surface of the second protrusion. The taper shape which inclined the side surface may be sufficient (It is still more desirable that the 2nd protrusion side surface is a plane or a curved surface).

  As yet another example, the second protrusion may be tapered by including a curved surface at its front end surface.

  In addition, when the cover part fits in the first opening, the part closest to the first projection part on the edge side surface of the groove opening surface that is the opening surface of the groove part is the side facing the first protruding plate at the inner edge piece. It is desirable to incline so that it becomes an obtuse angle with respect to one surface. It is more desirable that the inclined edge side surface includes a flat surface or a curved surface.

  Note that a thin display device on which the above-described stand for a thin display device is mounted can also be said to be the present invention.

  According to the present invention, the stand can be detached from the liquid crystal television. Therefore, for example, packaging is possible in a state where the liquid crystal television and the stand are separated, and the size of the packaging box is reduced. Therefore, the cost of the packaging box can be reduced, and furthermore, a large amount of the reduced packaging box can be loaded on the container of the transporting machine such as a truck, so that the transportation cost can be reduced.

  The pedestal portion 61 includes a main body 62, a recess portion 63 (a top-side recess portion 63 a and a bottom-side recess portion 63 b), and a main opening portion 71. The main body 62 is a main member of the pedestal portion 61, and the dent portion 63 is a dent formed on both the top surface (the pedestal top surface 62 a) and the bottom surface (the pedestal bottom surface 62 b) of the main body 62. The main opening 71 is a hole formed in the recess 63.

  Here, the cover part 21 will be described in detail with reference to FIGS. FIG. 2 is a plan view showing the cover top surface 23, and FIG. 3 is a plan view showing the outer wall 24. 4 is a cross-sectional view taken along line AA ′ of the cover part 21 shown in FIG. 2, and FIG. 5 is a cross-sectional view taken along line BB ′ showing the cover part 21 shown in FIG. . FIG. 6 is a perspective view showing the cover portion 21 in which the support portion 11 is accommodated.

  A direction in which the outer wall 24 extends from the cover top surface 23 is defined as an extending direction E. Further, the longitudinal direction of the cover top surface 23 is defined as a longitudinal direction L, and the short direction of the cover top surface 23 is defined as a short direction S.

  As shown in FIGS. 2, 3, 5, and 6, the cover portion 21 includes a cylindrical outer wall 24 and a cover top surface 23 that closes an edge of the outer wall 24. And space SS enclosed by the outer wall 24 and the cover top surface 23 accommodates the support part 11, as shown in FIG. And the support body 12 which is one end of the support part 11 is exposed from the exposed opening 22 of the cover top surface 23 (In addition, the cover part 21 is accommodated, fixing the support part 11).

  Further, the first protruding plate 31 protrudes from the outer wall 24. Specifically, the first protruding plate 31 is, for example, in the longitudinal direction in the vicinity of the bottom edge of the outer wall 24 (the hem of the outer wall 24) that extends from the short side of the cover top surface 23 slightly closer to the cover top surface 23 side. It protrudes along L. Further, the surface of the first projecting plate 31 and the cover top surface 23 are in a parallel relationship (however, the shape of the first projecting plate 31 is not particularly limited).

  Similar to the first protruding plate 31, the second protruding plate 41 also protrudes from the outer wall 24. Specifically, the second projecting plate 41 projects from the bottom edge of the outer wall 24 extending from the short side of the cover top surface 23 and is covered with the first projecting plate 31 (the second projecting plate 41). Has a plate opening 42 at a location covered by the first protruding plate). Therefore, a gap D is generated between the first protruding plate 31 and the second protruding plate 41 (however, the shape of the second protruding plate 41 is not particularly limited).

  The pedestal 61 and the cover 21 are connected to each other by sandwiching a part of the pedestal 61 in the gap D. The pedestal 61 will be described in detail with reference to FIGS. 7 is a plan view showing a pedestal top surface 62a of the main body 62 of the pedestal portion 61, and FIG. 8 is a plan view showing a pedestal bottom surface 62b on the back side of the pedestal top surface 62a. 9 is a cross-sectional view taken along the line CC ′ of the pedestal portion 61 shown in FIG. 7, and FIG. 10 is a perspective view showing a state in which the cover portion 21 has entered the main hole portion 71. .

  As shown in FIGS. 7 and 9, the pedestal top surface 62a is formed with a top side recessed portion 63a. On the other hand, as shown in FIGS. 8 and 9, a bottom-side depression 63b located on the back side of the top-side depression 63a is formed on the pedestal bottom surface 62b. And these top side hollow part 63a and bottom side hollow part 63b are hollow to such an extent that the thick part of the main body 62 pinched by both hollow parts 63a * 63b is made into plate shape.

  Furthermore, a main hole 71 is formed in the recess 63. The main opening 71 includes a first opening 72 and an open space 76. The first opening 72 is a hole wider than the outer periphery of the cover portion 21, that is, a hole wider than the periphery of the outer wall 24 including the fan-shaped second protruding plate 41. Therefore, as shown in FIG. 10, the cover portion 21 that accommodates the support portion 11 can enter the first opening 72.

  The open space portion 76 is a space for rotating the cover portion 21 entering the first open port 72 with reference to the center around the hem of the outer wall 24, for example. More specifically, in this rotation, the gap D between the first protruding plate 31 and the second protruding plate 41 is fitted to the edge (inner edge piece 81) of the open space portion 76, and the open space portion 76 is rotated. This is a space that prevents the outer wall 24 from coming into contact with the first opening 72.

  That is, when such a pedestal portion 61 and the cover portion 21 are included in the stand SD, as shown in FIG. 10, the cover portion 21 becomes the main opening portion 71 (specifically, the first opening 72). It becomes possible to enter, and by further rotating (refer to the arrow R direction), the gap D between the first protruding plate 31 and the second protruding plate 41 and the inner edge piece 81 of the open space 76 can be fitted. Therefore, the base part 61 and the cover part 21 are connected.

  Therefore, such a stand SD can be attached to the liquid crystal television 90 itself only when the liquid crystal television 90 is installed. Conversely, the stand SD may be detached from the liquid crystal television 90 except when the liquid crystal television 90 is installed. That is, the stand SD can be attached to and detached from the liquid crystal television 90.

  Therefore, for example, packaging is possible in a state where the liquid crystal television 90 attached with the cover portion 21 to which the support portion 11 is attached and the pedestal portion 61 are separated, and the size of the packaging box is reduced. Then, the cost reduction of the packaging box which became small can be aimed at. In addition, if the packaging box is reduced in size, it can be loaded in a larger amount than a container of a transport machine such as a truck, so that the transportation cost can be reduced.

  Moreover, the cover part 21 and the base part 61 in this stand SD are connected, without using fastening members, such as a screw. Therefore, the stand SD is attached to the liquid crystal television 90 without imposing a burden on the user or the like.

  In addition, in order to strengthen the connection between the pedestal portion 61 and the cover portion 21, the first protrusion plate BG <b> 1 is formed on the first protrusion plate 31 on the one surface 32 facing the plate opening 42 of the second protrusion plate 41, It is desirable that a groove portion VY into which the first protrusion BG1 is fitted is formed on one surface (front surface) 82 of the inner edge piece 81 on the side facing the first protruding plate 31 (FIGS. 3 to 5 and 7 to 7). 9 etc.). Further, it is desirable that a second protrusion BG2 that fits into the plate opening 42 of the second protruding plate 41 is formed on the one surface (back surface) 83 on the side facing the second protruding plate 41 in the inner edge piece 81. .

  11 is a cross-sectional view of FIG. 11 showing the cover portion 21 and the pedestal portion 61 that rotate after entering the main opening portion 71 (a cross section viewed from the same direction as the cross-sectional views of FIGS. 4 and 9). As described above, the first protrusion BG1 included in the cover portion 21 fits into the groove VY included in the pedestal portion 61, and the plate opening 42 included in the cover portion 21 fits into the second protrusion BG2. Therefore, the cover portion 21 is difficult to move in the in-plane direction of the one surface 82 or 83 in the inner edge piece 81 (in short, the cover portion 21 is immovable with respect to the pedestal portion 61).

[Other embodiments]
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, the first protrusion BG1 of the first protrusion plate 31 is preferably tapered toward the protrusion tip. If it becomes like this, side BG1a of the 1st projection part BG1 will incline with respect to one surface (surface) 82 of the inner edge piece 81 in the base part 61, and 1st projection part BG1 which has side BG1a has become. It can be easily moved on the surface 82 of the inner edge piece 81.

  As an example of such a tapered first protrusion BG1, as shown in FIG. 12, the area of the first protrusion tip surface BG1b, which is the surface of the protrusion tip of the first protrusion BG1, is set as a protrusion. You may taper by narrowing rather than 1st process | protrusion root surface BG1c which is a base surface. That is, the first protrusion BG1 may be inclined with respect to the first protrusion side BG1a, which is its own side (note that the first protrusion side BG1a is not limited to a plane as shown in FIG. Good).

  Alternatively, as shown in FIG. 13, the tapered first protrusion BG1 may include a curved surface on the first protrusion tip end surface BG1b.

  Further, as shown in FIGS. 12 and 13, when the cover portion 21 is accommodated in the first opening 72 (see FIG. 10), the portion closest to the inner edge piece 81 on the side surface of the outer edge of the second protruding plate 41 ( It is desirable that the portion 41 a) is inclined so as to have an acute angle (δ) with respect to the bottom surface 41 c of the second protruding plate 41. That is, it is desirable that the portion 41a is tapered by being inclined.

  If it becomes like this, the inclined side surface part 41a will be easy to rise to the 2nd projection part BG2 of the inner edge piece 81 in the base part 61, and the plate opening 42 fits easily in the 2nd projection part BG2.

  However, the inclined side surface portion 41a is not limited to a flat surface as shown in FIGS. 12 and 13, and may be a curved surface as shown in FIG. Further, it is desirable that the inner wall 42a in the plate opening 42 is also an inclined surface inclined outward (inclined so as to approach the portion 41a) as shown in FIG. 14 (this inclined surface is flat or curved). It may be)

  Further, it is desirable that the second protrusion BG2 be tapered toward the tip of the protrusion, like the first protrusion BG1. If it becomes like this, the side part 41a of the 2nd protrusion plate 41 will be easy to go up to 2nd protrusion part BG2, and the plate opening 42 of the 2nd protrusion plate 41 will be easy to 2nd protrusion part BG2 further. Fits into.

  As an example of such a tapered second projection BG2, as shown in FIG. 15, the area of the second projection tip surface BG2b, which is the projection tip surface of the second projection BG2, is defined as a projection. You may taper by narrowing rather than 2nd process | protrusion root surface BG2c which is a base surface. In other words, the second protrusion BG2 may be inclined with respect to the second protrusion side face BG2a that is the side face of the second protrusion part BG2 (note that the second protrusion side face BG2a is not limited to a plane as shown in FIG. Good).

  Alternatively, as shown in FIG. 16, the tapered second protrusion BG2 may include a curved surface on the second protrusion tip surface BG2b.

  Further, as shown in FIGS. 15 and 16, on the edge side surface of the groove opening surface VYa that is the opening surface of the groove portion VY, the portion VYaa that the first protrusion BG <b> 1 first contacts is the first on the inner edge piece 81. It is desirable to incline so as to have an obtuse angle (θ) with respect to the one surface 82 on the side facing the protruding plate 31. This is because the groove opening surface VYa that is the entrance of the groove VY is widened and the first protrusion BG1 is easily slid into the groove VY.

  However, the inclined side surface VYaa is not limited to a flat surface as shown in FIGS. 15 and 16, and may be a curved surface as shown in FIG.

  In the above, there are two sets of the first protruding plate 31 and the second protruding plate 41 that generate the gap D and the inner edge piece 81 that fits in the gap D. It is not a thing. That is, this set may be three or more sets.

  Finally, it goes without saying that embodiments obtained by appropriately combining the techniques disclosed above are also included in the technical scope of the present invention.
