The protruding fastening members 410, 710, and 810 can couple the case top 40 to other modules without separate screws or nuts. In one embodiment, when the case top 40 is manufactured to form the exterior of the display device, a protruding fastening member in the shape of a hook may be placed at a certain position on the case top 40. In order to prevent quality deterioration due to shrinkage during the injection and molding process and to reinforce the rigidity of the fastening member, the fastening member is shaped like a hook, and includes a connecting part and a support part in a "ㄷ" shape, a "ㅜ" shape, Alternatively, it can be designed in an “L” shape.

Conventionally, in order to combine the case top 40 with other modules, an assembly process using existing insert nuts and screws was required. However, when applying the fastening member of the present invention described above, a protruding hook type is used. Since the fastening members are integrally placed on the case top 40, there is no need to manufacture separate fastening members, and machines or personnel for fastening work, such as screws, are not required, thereby increasing the efficiency of the process.

Meanwhile, in order to construct the protruding fastening member according to an embodiment of the present invention, the case top 40 can be manufactured through mold and injection. On the inside of the case top, a protruding fastening member having a hook-like shape in one embodiment may be disposed integrally with the case top. It can be manufactured through molding and injection rather than through a press method to form a protruding area such as a hook.

Additionally, during the molding process, a groove may be placed in a portion of the case top 40. That is, when the case top 40 is composed of two surfaces, an embodiment in which protruding fastening members are disposed on both the first and second surfaces (see FIG. 4), or a protruding fastening member is placed on the first side, The embodiment in which the groove is disposed on the second surface (see FIG. 5) all corresponds to the embodiment of the present invention. In addition, as shown in FIGS. 6 to 8, a first surface is disposed opposite the display panel, and at least one protruding fastening member in the shape of “ㄷ”, “ㄱ”, and “ㅜ” as seen above is provided on the first surface. It can be arranged, and the coupling portion of the protruding fastening member can be configured to extend along the If the coupling part is arranged long, the coupling strength can be increased. On the other hand, when the coupling part of one protruding fastening member is long, a support part must be arranged to support it, so the protruding fastening members are arranged on the first side at a set interval according to the size of the support part and the coupling part and the required coupling force. It can be.

In another embodiment of the present invention, the protruding fastening member may be disposed long in the “Y” axis direction of FIGS. 6 to 8. This can be determined depending on how the case top is combined with other modules. In this case, the support part may be arranged in the X-axis direction, and the coupling part may be arranged in the Y-axis direction.

A plurality of protruding fastening members may be disposed on the first surface where the protruding fastening members shown in FIGS. 6 to 8 are integrally disposed or on the second surface, which is another surface. Additionally, these protruding fastening members may vary in size depending on where they are placed.

Figure 9 is a diagram showing a configuration in which a protruding fastening member according to an embodiment of the present invention has different heights or widths depending on the position of the case top.

In Figure 9, three protruding fastening members 911, 912, and 913 are arranged. The sizes of these fastening members 911, 912, and 913 can be identified by the height of the coupling portion (h1, h2, h3) or the area of the coupling portion (d1, d2, d3). And as shown in Figure 9, in the embodiment of the present invention, the height (h1, h2, h3) or area (d1, d2, d3) of the coupling portion of the plurality of protruding fastening members 911, 912, and 913 may be configured differently. You can.

When the protruding fastening members disposed on the case top 40 are combined with other modules, the external force applied may be different or the coupling force required for each protruding fastening member may be different, so it can be configured appropriately. . In one embodiment, the height and width of the protruding fastening member disposed at the center may be configured to be larger than the height and width of the protruding fastening member disposed at the outer portion. Additionally, according to another embodiment, when the display panel 10 coupled to the case top 40 has a curved structure rather than a flat structure, the protruding fastening member disposed on the outer portion may require stronger coupling force, The height and width of the protruding fastening member disposed in the portion can be configured to be larger than the height and width of the protruding fastening member disposed in the center. As shown in Figure 9, the coupling force between the case top 40 and other modules can be increased by adjusting the size of the protruding fastening member disposed on the case top 40.

To summarize Figure 9, a case top having a first side and a second side may have two or more protruding fastening members disposed on the first side. The heights of these protruding fastening members may be different. As shown in Figure 9, the height of the protruding fastening member is determined by the relationship between the coupling part inserted into the groove disposed on the guide panel and one or more supports supporting it, and the length of the tangent between the coupling part and the support part is that of the protruding fastening member. It can be high. Depending on the degree to which the protruding fastening member maintains bonding force and has elasticity for bonding. Protruding fastening members can be designed to have different heights. In particular, in the case of a curved display panel, the coupling force required to couple the case top 40 to the guide panel 30 may vary depending on the area of the case top 40. To this end, in the embodiment of the present invention, the sizes of the protruding fastening members can be varied to provide different coupling forces in the case top 40. Of course, adjusting the coupling force in the case top 40 by increasing the number of protruding fastening members or the density in the area of the protruding fastening members also corresponds to one embodiment.

Figure 10 is a diagram showing a structure in which protruding fastening members are integrally disposed on both sides of the case top according to an embodiment of the present invention.

The case top may be composed of a first side and a second side, and a protruding fastening member may be disposed on the first side as shown in FIGS. 6 to 8. Meanwhile, as shown in FIG. 10 , a protruding fastening member 420 may also be disposed on the second surface.

Towers can be combined. Since the protruding fastening members 410 and 420 on two sides are coupled to the guide panel 30 and/or the rear support, the case top can be firmly coupled with other modules.

Figure 11 is a diagram showing a structure in which a groove-shaped fastening member is disposed on one of the two sides of a case top according to another embodiment of the present invention. See Figure 5. As described above, a protruding fastening member may be disposed on the first surface as shown in FIGS. 6 to 8. Meanwhile, as shown in FIG. 11, a groove-shaped fastening member may be disposed at 521 on the second surface. A groove-type fastening member 521 is disposed on the second side, and as shown in FIG. 5, the case top can be coupled to the guide panel 30 and the rear support using the groove-type fastening member 521 on the second side. . To this end, the separate fastening member 520 protruding from the guide panel 30 is coupled with the groove-shaped fastening member 521 of the case top, so that the case top can be firmly coupled with other modules.

Figure 12 is a diagram showing various configurations of a protruding fastening member according to an embodiment of the present invention. In Figures 6 to 8, it was seen that the protruding fastening member is composed of a coupling part and a support part. Meanwhile, in Figure 12, we will look at an embodiment in which the height of the support portion is smaller than the height of the coupling portion.

1201, 1202, and 1203 all present support parts 1220a, 1220b, 1220c, and 1220d coupled to one coupling part 610. They all have a height of h5 that is smaller than h4, which is the height of the coupling portion 610. This can lower the height of the support parts 1220a, 1220b, 1220c, and 1220d so that the coupling part 610 can have elasticity in the process of being inserted into the groove arranged in the guide panel. Therefore, the protruding fastening member according to an embodiment of the present invention includes a coupling portion and a support portion inserted into a groove disposed on the guide panel, and the support portion supports the coupling portion and has a lower height than the coupling portion (see FIG. 12 ) or may have the same height (see FIGS. 6 to 8).

Figure 13 is a diagram showing the shape of a support portion of a protruding fastening member according to another embodiment of the present invention. During the injection process using a mold, the supports 1320a and 1320b may have an inclined shape. That is, during the injection process, the coupling portion 610 maintains its height, but the support portions 1320a and 1320b have the same height as the coupling portion 610 in the portion adjacent to the coupling portion 610, and the height increases toward the end. It can have a shrinking shape.

When applying the embodiment of the present invention, injection molding using a mold can be applied instead of compression molding using metal, and a protruding fastening member such as a hook shape is integrally placed on the inside of the front of the case top, and a separate nut is installed. The case top can be combined with other modules without screws. Additionally, in order to increase the coupling force of the protruding fastening member, the coupling force that the case top must provide can be diversified by varying the size or shape of the protruding fastening member. In particular, in the case of a curved display panel, the bonding force that the case top must provide may differ depending on the area, and for this purpose, the height, width, or spacing of the protruding fastening members placed on the case top can be adjusted.

Although the above description focuses on the embodiments of the present invention, various changes and modifications can be made at the level of those skilled in the art. Accordingly, it will be understood that such changes and modifications are included within the scope of the present invention as long as they do not depart from the scope of the present invention.
