Description

  The present invention relates to a display device, and more particularly, to a display device including a stand unit in which a display body including a liquid crystal panel is connected to the cabinet.

  In the field of this type of display device, various structures of the connecting portion between the display main body and the stand unit have been proposed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).

  Among these, Patent Document 1 describes a display device, which generates electromagnetic interference waves by interposing an insulating structure portion on a stand column supporting a conductive metal casing provided with a front glass. It is to suppress. Patent Document 2 describes a flat display having a base stand, and in this case, a display panel is attached to the base stand by fitting a fixture provided on the display panel side into the opening of the base stand. Yes. Patent Document 3 describes a display with a support base. In this display, left and right metal leg bodies are projected upward on a metal base, and mounting members provided on the leg bodies are vertically mounted on the display. Screws are attached at two locations, and a connecting plate is provided to help maintain the distance between the two leg bodies.

By the way, in a display device employing a liquid crystal display (LCD), when a cabinet to which a liquid crystal panel is attached is formed of a resin molded body, the cabinet is subject to various types of deformation required for the display device, such as twisting and shaking. It has been found that there is a risk that the performance may be impaired or the viewing sensation for the user may be impaired. It is also known that cabinet deformation can occur due to changes in temperature or heat inside the cabinet.

  Therefore, with the intention of increasing the strength of the cabinet made of a resin molded body, the shape of the cabinet is devised to provide unevenness of a three-dimensional structure, or the reinforcing ribs are molded integrally, etc. However, there are limits to preventing subsequent deformation such as twisting of the cabinet and shaking movement of the cabinet supported by the stand unit only by taking such measures. In this regard, the techniques proposed in Patent Document 1 and Patent Document 2 are not intended to prevent the cabinet from being deformed or shaken.

  On the other hand, in the technique proposed in Patent Document 3, the base of the support base as a stand unit and the leg main body are both made of metal, and the mutual distance is maintained by a connecting plate horizontally placed between the two, and Since the display is prevented from falling by screwing the display to the leg body via the mounting member, the display is reinforced to some extent by the support base composed of the leg body, the connecting plate, and the mounting member. it is conceivable that.

  However, in the technology proposed in Patent Document 3, the support base as a stand unit is provided with an attachment member in addition to the metal leg body as well as the metal leg main body, thereby ensuring strength. The number of types of metal components required for this is three types. For this reason, there is a problem that the number of assembling steps increases correspondingly and the manufacturing cost increases. In addition, the above mounting members are only screwed in two overlapping places on the left and right sides of the back of the display (equivalent to a cabinet), so sufficient measures are taken from the viewpoint of preventing deformation and shaking of the display. It cannot be said that it is done. That is, in such a screw-fixing structure, the left and right mounting members only serve to maintain the planar shape of the display, and the display itself is provided with a configuration for preventing deformation and shaking movement of the display itself. As such, it is not satisfactory in terms of reliability in preventing deformation and shaking of the display.

  The present invention has been made in view of the above situation, and prevents the cabinet from being deformed or swayed by both the reinforcing action of the stand unit connected to the cabinet by screws and the structural reinforcing action of the cabinet itself. It is an object of the present invention to provide a display device that can be used.

  Another object of the present invention is to provide a display device that has an effect of preventing the deformation and swinging of the cabinet from that of the above-mentioned Patent Document 3 and uses only a smaller number of components. And

  The display device according to the present invention includes a stand unit in which a display main body is connected to the cabinet. And one side of each sheet metal leg piece raised from the left and right two places of the sheet metal base plate is superimposed on each of the two left and right places on the back of the lower end of the cabinet, and the overlapping places are screwed. A sheet metal support piece bent forward at the edge of the leg piece in the width direction to reinforce the leg piece is fitted into a groove provided in the cabinet, and formed in the support piece part. A contact portion formed in the groove portion of the cabinet is placed on the stepped receiving portion, and the stand unit includes the base plate, the leg piece, and the support piece portion. It has.

  With this configuration, the number of types of metal parts required to secure the strength to support the cabinet is only two types: the base plate and the leg pieces having the support piece portions. It is less than that of the support platform found in Document 3. In addition to the fact that the left and right leg pieces are screwed to the back of the cabinet, the support piece parts of the leg pieces are fitted into the grooves provided in the cabinet, so that the support piece parts are legged. Not only is it useful for reinforcing the piece, but the supporting piece and the groove are meshed to reinforce the cabinet and prevent its deformation, and the cabinet itself is reinforced and deformed by the groove. It becomes difficult. For this reason, deformation and shaking of the cabinet are prevented by both the reinforcing action by the stand unit connected to the cabinet by screws and the structural reinforcing action of the cabinet itself.

  In addition, the structure in which the contact portion formed in the groove portion of the cabinet is mounted on the stepped receiving portion formed in the support piece portion makes it difficult for the cabinet to fall forward and the cabinet. There is also an advantage that an unreasonable force is not easily applied to the cabinet because the weight of the steel can be received not only by the screw fixing portion but also by the receiving portion.

  In the present invention, the contact portion is mounted on the receiving portion, and one side of the leg piece is overlapped on the back of the lower end of the cabinet, so that a screw hole on the back of the lower end of the cabinet is opened in the leg piece. It is desirable that the screw is inserted into the screw insertion hole, and the screwing operation when connecting the stand unit to the cabinet can be easily performed.

  In the present invention, the support piece portion is formed with a narrow rib portion on the upper side of the stepped receiving portion as a boundary and a wide rib portion on the lower side of the receiving portion. It is desirable that the deep wall surface of the groove portion located on the lower side of the section is in contact with and overlaps with the front end surface of the wide rib portion, and according to this, the lower end portion of the cabinet is backed up from behind by the support piece portion Now, it will be more difficult for the cabinet to fall forward.

  The present invention is further embodied by adopting the following configuration. That is, in a display device in which the display main body includes a stand unit connected to the cabinet, the base plate made of sheet metal mounted on the installation surface of the display device at each of the two left and right sides of the back of the lower end of the cabinet One side of each sheet metal leg piece raised from the two left and right sides is overlapped, and the overlapping part is screwed at two places at the top and bottom, and is bent forward at the edges in the width direction of each leg piece A pair of left and right sheet metal rib-shaped support pieces for reinforcing the leg pieces are respectively fitted into two groove portions provided on both sides of the overlapping portion of the cabinet, and the support piece portions. Is formed with a narrow rib portion on the upper side of the stepped receiving portion formed in the middle portion in the vertical direction and a wide rib portion on the lower side of the receiving portion. A contact portion formed in the groove portion of the cabinet is placed on the receiving portion, and the back wall surface of the groove portion located below the contact portion is in contact with the front end surface of the wide rib portion. A screw hole on the back of the lower end of the cabinet is opened in the leg piece by overlapping and placing the contact part on the receiving part and superimposing one side of the leg piece on the back of the lower end of the cabinet. The stand unit includes the base plate, the leg piece, and the support piece portion, and the stand unit includes the base. A cover body that covers the plate and the back portion of the leg piece and the support piece portion is added, and the cover body is fixed to the leg piece with a mounting screw that fastens the overlapping portion with a screw. It is further embodied by use. The effect | action of this invention is demonstrated in detail with reference to embodiment mentioned later.

  According to the present invention, the deformation and shaking movement of the cabinet is prevented by both the reinforcing action by the stand unit connected to the cabinet by screws and the structural reinforcing action of the cabinet itself, so that the deformation and shaking movement of the display is prevented. The reliability in preventing the problem is improved. In addition, since such reliability is improved by using only a small number of types of metal parts, the number of man-hours required for assembly is less than that found in Patent Document 3, and the manufacturing cost can be reduced accordingly. .

The cabinet 1 is attached with a liquid crystal panel together with the liquid crystal panel. Configure the display body. The stand unit 3 is connected to the cabinet 1.

  As shown in FIG. 6 and FIG. 7 in addition to FIG. 1, the cabinet 1 is formed as an overhanging structure portion 12 in which a portion excluding the peripheral portion protrudes backward, and the overhanging structure portion 12 is the cabinet. It helps to reinforce the whole and prevent its deformation.

  Next, the stand unit 3 shown in FIG. 2 will be described. The stand unit 3 includes a sheet metal base plate 4 shown in FIG. 4, separate sheet metal leg pieces 5 and 5 raised from the left and right portions of the base plate 4, and the leg pieces. 5 are provided with rib-like support piece portions 6 and 6 which are bent forward at both end edges in the width direction to reinforce the leg pieces 5. Further, as shown in FIG. 5, the leg piece 5 has attachment pieces 51, 51 provided at the lower ends of the left and right support piece portions 6, 6, and these attachment pieces 51, 51 are 4 and FIG. 8 or FIG. 9 are overlapped with the base plate 4 and firmly screwed so that a plurality of overlapping portions do not wobble. Further, the base plate 4 itself is formed by cutting and forming ribs 41 along the peripheral edge thereof, and is reinforced so as not to be easily deformed by the ribs 41.

  Further, as shown in FIG. 5, each of the support piece portions 6 described above has a stepped horizontal receiving portion 61 formed in the middle portion in the vertical direction, and the receiving portion 61 serves as a boundary. The upper side of the receiving part 61 is formed as a narrow rib part 62, and the lower side of the receiving part 61 is formed as a wide rib part 63.

  As shown in FIG. 2 or 3, a cover body 7 is added to the stand unit 3. The cover body 7 includes a base cover portion 71 that covers the entire base plate 4 from above, a skirt portion 72 that covers a lower portion of the leg piece 5, and the back portions of the leg piece 5 and the support piece portion 6. It is a hollow resin molded body that is integrally provided with a rising portion 73 that is a covering portion. As shown in FIG. 5, a slit-like shape through which the leg piece 5 and the supporting piece portion 6 are inserted into the skirt portion 72. In addition to the opening 75 being formed in a U-shape, the rising portion 73 penetrates a recess 76 opened at the back and top surfaces thereof and a front wall 77 forming the back wall of the recess 76. Two screw insertion holes 78, 78 are provided on the upper and lower sides.

  The cover body 7 is placed on the base plate 4 by inserting the openings 75 of the left and right skirt portions 72 through the left and right support piece portions 6 and the leg pieces 5 respectively, and the base plate 4 is screwed at a predetermined location. Stopped. When the cover body 7 is thus mounted on the base plate 4, the leg piece 5 and the left and right support pieces 6, 6 of the leg piece 5 protrude above the skirt portion 72 as shown in FIG. 2 or 3. On the other hand, the other parts, that is, the base plate 4, the lower part of the leg piece 5 and the support piece 6 are covered with the cover body 7 and cannot be seen from the outside. Therefore, the cover body 7 is not only a component of the stand unit 3 but also an element that determines the overall design of the stand unit 3. In the stand unit 3 to which the cover body 7 is attached, the screw insertion holes 52 and 52 provided at the two upper and lower positions of the leg piece 5 are the screw insertion holes 78 and two at the upper and lower positions of the front wall 77. 78 overlaps.

  Next, the structure of the connecting portion between the cabinet 1 and the stand unit 3 will be described.

  As shown in FIG. 8, in this connecting portion, the front surface (one surface) 53 of the leg piece 5 raised from the base plate 4 is superimposed on the rear surface of the lower end of the cabinet 1, and the overlapping portion (see FIG. 7). ), The mounting screw 81 inserted through the screw insertion holes 78 and 78 provided in the front wall 77 of the rising portion 73 and the screw insertion hole 52 of the leg piece 5 is a boss portion provided at the lower end portion of the cabinet 1. 13 is screwed in and screwed in two places at the top and bottom. Further, as shown in FIG. 7, the left and right support piece portions 6 and 6 of the leg piece 5 are individually fitted into the vertically long groove portions 14 and 14 provided on the left and right sides of the above-described overlapping portion i. Then, as shown in FIG. 9, a downward contact portion 15 formed in a stepped manner in the groove portion 14 is placed on the receiving portion 61 of the support piece portion 6, and the contact portion 15 The rear wall surface 16 of the groove portion 14 positioned on the lower side is in contact with and overlaps the front end surface 64 of the wide rib portion 63.

  In the display device having this configuration, when the contact portion 15 is mounted on the receiving portion 61 and the front surface 53 of the leg piece 5 is superimposed on the rear surface of the lower end portion of the cabinet 1, the boss 13 on the rear surface side of the cabinet 1 is alone. The screw hole is aligned with the screw insertion hole 52 of the leg piece 5. Therefore, when performing the screwing operation for connecting the stand unit 3 to the cabinet 1, the support piece 6 is fitted into the groove 14 of the cabinet 1 and the contact portion 15 is mounted on the receiving portion 61. 13 screw holes and the screw insertion holes 52 of the leg pieces 5 are overlapped, and there is an advantage in the work process that the screwing operation can be performed immediately without positioning them.

  In this embodiment, there are two types of metal parts included in the stand unit 3, that is, a base plate 4 and a leg piece 5 having a support piece 6, and the cabinet 1 is supported only by these two types of metal parts. Strength is secured. Therefore, the stunt unit 3 that supports the cabinet 1 with a small number of metal parts is configured.

  The left and right leg pieces 5 and 5 fixed to one base plate 4 are screwed at two places on the back of the lower end portion of the cabinet 1, so that the deformation of the cabinet 1 is changed to the leg pieces 5. , 5 is blocked. Moreover, in addition to that, since the left and right support pieces 6 and 6 of the left and right leg pieces 5 and 5 are respectively fitted in the groove portions 14 and 14 formed in the cabinet 1, The support piece portions 6 and 6 not only serve to reinforce the leg piece 5, but also the support piece portions 6 and 6 and the groove portions 14 and 14 mesh with each other so that the support piece portions 6 and 6 become the cabinet 1. It is also useful to reinforce and prevent deformation. In addition, the cabinet 1 itself is reinforced in shape by the grooves 14 and 14 and is not easily deformed. For these reasons, the deformation of the cabinet 1 is prevented by both the reinforcing action by the stand unit 3 connected to the cabinet 1 by screws and the geometrical or structural reinforcing action of the cabinet 1 itself. It can be said that

  Further, the configuration in which the contact portion 15 on the cabinet 1 side is mounted on the receiving portion 61 of the support piece portion 6 prevents the cabinet 1 from being tilted forward. In addition, this configuration allows the weight of the cabinet 1 to be reduced. It is difficult to apply an excessive force to the cabinet 1 because it is received not only by the screw fixing portion 81 but also by the receiving portion 61. Further, the cabinet 1 is more unlikely to fall forward because the rear wall surface 16 of the groove 14 on the cabinet 1 side is in contact with and overlaps the front end face 64 of the wide rib portion 63 of the support piece 6.

  In this embodiment, the left and right support pieces 6, 6 provided on the leg piece 5 are fitted into the two groove portions 14, 14 on the cabinet 1 side so as to sandwich the overlapping portion a shown in FIG. 7. It is also possible to adopt a configuration, and by doing so, it has been found that the cabinet 1 becomes more difficult to deform due to the squeezing action of the overlapping portion i by the left and right support pieces 6, 6. .
