The case top 500 is made of a metal material with sufficient rigidity and, for example, may be made of an extruded aluminum frame.

In particular, the fastening portion 510 forms a groove-shaped sliding rail 530 into which the stand 600 is slidably inserted in the longitudinal direction. The sliding rail 530 forms a pair of separation prevention flanges 540 facing each other on the left and right sides to prevent the inserted stand 600 from coming off.

In addition, a fastening slit 550 is formed in the separation prevention flange 540 into which the fixing member 640 that secures the stand 600 is fastened. The fastening slit 550 may be formed to have a predetermined width and length along the longitudinal direction of the separation prevention flange 540. Additionally, the fastening slit 550 may be formed as one continuous slit along the longitudinal direction, but in this embodiment, it is formed divided into a plurality of slits having a predetermined length. When the fastening slit 550 is formed as a single slit with a long length, the supporting force of the separation prevention flange 540 may be weakened by the fastening slit 550, but when it is formed by dividing it into multiple pieces with a predetermined length. The support force of the separation prevention flange 540 can be maintained.

Therefore, the stand 600 can be fixed by the fixing member 640 at any position while being inserted into the sliding rail 530 along the longitudinal direction of the case top 500, so a position at which the stand 600 is fixed is required. There is an advantage in being able to select and change depending on the situation.

The stand 600 is coupled to the case top 500 to support the display device so that it can stand stably on the structure. As shown in FIG. 6, the stand 600 is inserted into the sliding rail 530 of the case top 500. It consists of a sliding insertion portion 610 and a leg portion 620 supported by the structure, and the sliding insertion portion 610 and the leg portion 620 may be integrally connected via a neck 630.

The sliding insertion portion 610 may have a plate shape with a predetermined width, thickness, and length, and generally has a slightly smaller width and thickness corresponding to the width and thickness of the sliding rail 530. The sliding insertion part 610 has a plurality of fastening holes 611 into which the fixing member 640 is fastened and fixed.

The leg portion 620 may be composed of a first leg 621 that obliquely extends forward from the neck 630 to a predetermined length and a second leg 622 that obliquely extends rearward to a predetermined length. The leg 621 and the second leg 622 form a predetermined inclination angle.

The display device configured as described above can be installed stably by having a pair of stands 600 fixed to the case top 600 on the left and right sides and being supported on the surface of the structure.

Figure 7 is a diagram showing the stand assembly process of the display device according to this embodiment, Figure 8 is a cross-sectional view showing the fastening structure of the case top and the stand according to this embodiment, and Figure 9 is a view showing the case top and stand according to this embodiment. This is a bottom view showing the fastening structure of the stand.

Referring to FIG. 7, the stand 600 is fastened at both left and right ends of the case top 500 so that the sliding insertion portion 610 is inserted along the sliding rail 530. At this time, a pair of left and right stands 600 are inserted to a position where a predetermined distance is maintained depending on the structure where the display device is installed, and after the position of the stand 600 is determined, the fixing member 640 is fastened to secure the stand 600. ) is fixed. The fixing member 640 is fastened to the fastening hole 611 through the fastening slit 550 so that the stand 600 is fixed to the case top 500. The fixing member 640 may be composed of a screw.

The stands 600 fastened in this way are fixed at positions opposing each other in the left and right directions about the center of the display device, and thus can stably support the display device. Additionally, the stand 600 can be fixed at any position selected as needed, so it can be mounted on structures of various types or sizes.

Meanwhile, in order for the stand 600 to be stably fixed to the case top 500 and to support the display device with sufficient support force, the thickness, width, and length of the sliding insertion portion 610 and the sliding rail 530, and the fastening slit 550 ) must be set appropriately in length.

Referring to FIG. 8, the sliding insertion portion 610 is preferably formed to have a thickness (A) of at least 2 mm or more and a width (C) in the front-back direction of 10 mm or more. In addition, the sliding rail 530 has a thickness (B) that is approximately 0.2 mm larger than the thickness (A) of the sliding insertion portion 610 (B=A+0.2mm), and the width (C) of the sliding insertion portion 610 It is preferably formed to have a width (D) greater than about 0.4 mm (D=C+0.4). When the sliding insertion portion 610 and the sliding rail 530 are formed with the above dimensions, the movement or clearance of the stand 600 fastened to the case top 500 is minimized and the support force of the stand 600 is lost. It is delivered to the case top 500 without any charge, so that the display device can be stably supported.

In addition, referring to FIG. 9, in the longitudinal direction of the case top 500, a plurality of fastening slits 550 are formed separated by a predetermined length, and the length (E) of each fastening slit 550 is 40 mm to 60 mm. It is desirable to separate them into units, preferably 50 mm. If the fastening slit 550 has a length of less than 40 mm, the supporting force of the separation prevention flange 540 may be strengthened, but the distance at which the stand 600 can move is short, which may cause restrictions in positioning the stand 600. , if it has a length exceeding 60 mm, it is advantageous to select a fixing position for the stand 600, but the supporting force of the separation prevention flange 540 may be weakened.

In addition, the sliding insertion portion 610 is preferably formed to have a length F of 10 mm or more in both directions centering on the leg portion 620. The longer the length (F) of the sliding insertion portion (610), the more advantageous in terms of stable support, but if it exceeds 1/2 of the length (E) of the fastening slit (550), it is meaningless because the fixing member (640) cannot be fastened. If the length (F) is more than 10 mm, the fixing force may be weakened. Therefore, the sliding insertion portion 610 is preferably formed to have a length of 10 mm to 20 mm in both left and right directions centering on the leg portion 620 (10 mm≤F≤20mm).

Although exemplary embodiments of the present invention have been shown and described as described above, various modifications and other embodiments will occur to those skilled in the art. These modifications and other embodiments are to be considered and included in the appended claims without departing from the true spirit and scope of the present invention.
