Description

  The present invention relates to a display stand for installing a display, and more particularly to a display stand provided with a pedestal. Moreover, it is related with the display system provided with such a display stand and a display. The present invention also relates to a method for manufacturing such a display stand.

  Display stands are widely used to install displays such as liquid crystal displays and organic EL displays. As a display stand for installing the display on a horizontal surface (surface parallel to the ground) such as a shelf board, a pedestal (hereinafter also referred to as “stand pedestal”) placed on the horizontal surface, and a stand on the pedestal In general, a display stand is configured to include a support post and a display attached to the support post. Such a display stand may be shipped as a display system together with a display.

  In such a display system, making both the display and the display stand excellent in aesthetics is an important differentiating factor in the market. For this reason, a narrow frame is required for a display, and a thin stand base is required for a display stand.

  However, if the stand pedestal is made thinner, the problem arises that the strength required to support the display cannot be secured. Therefore, a method of improving the strength of the display stand by welding a reinforcing plate to the bottom plate of the stand base is used.

  Examples of techniques that can be used for welding the bottom plate and the reinforcing plate constituting the stand base include those described in Patent Documents 1 and 2, for example.

  Patent Document 1 discloses a welding method for welding two steel plate components arranged to face each other. According to the welding method described in Patent Document 1, it is possible to prevent dripping of weld metal that may occur when two steel plate parts are welded by using a support device.

  Patent Document 2 discloses a welding method in which an end surface of a container main body and an end surface of a lid that forms a sealed container together with the container main body are welded. According to the welding method described in Patent Document 2, the surface of the welded portion can be smoothed by processing the end surfaces of the container main body and the lid into a special shape.

JP 5-38572 A (published February 19, 1993) JP 2008-223716 A (September 25, 2008)

  However, when the bottom plate and the reinforcing plate constituting the stand pedestal are welded using the welding method described in Patent Document 1, welding marks are formed on the surface of the bottom plate or the reinforcing plate so as to protrude in the shape of a knob. For this reason, when using the structure itself which consists of a baseplate and a reinforcement board as a stand base, the problem that the beauty | look of a stand base is impaired by this welding trace arises. Moreover, when using as a stand base what covered the structure which consists of a baseplate and a reinforcement board with the resin-made covers, the mounting | wearing of a cover will be inhibited by this welding trace. Furthermore, the welding method described in Patent Document 1 has a problem that the degree of difficulty in welding work is high. This is because it is necessary to arrange the support equipment at an appropriate position during welding.

  Moreover, the welding method described in Patent Document 2 is for welding end faces of members, and is not suitable for welding between a bottom plate and a reinforcing plate arranged so as to face each other. Furthermore, the welding method described in Patent Document 2 has a problem of high welding costs. This is because it is necessary to process the end face of the member to be welded into a special shape.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a display stand that maintains its aesthetics and ensures strength.

  In order to solve the above problems, a display stand according to an aspect of the present invention is a display stand including a pedestal, wherein the pedestal includes a metal bottom plate having a side wall and the side wall so as to face the bottom plate. A reinforcing plate made of metal disposed in a space surrounded by the outer periphery of the reinforcing plate, and the outer peripheral portion of the reinforcing plate is formed with a depressed portion that is depressed toward the bottom plate. The depressed portion and the inner wall surface of the side wall are welded.

  In order to solve the above-described problem, a manufacturing method according to an aspect of the present invention is a method for manufacturing a display stand including a pedestal, wherein the metal bottom plate having side walls and the bottom plate are opposed to each other. It includes a welding step of manufacturing the pedestal by welding a metal reinforcing plate disposed in a space surrounded by side walls, and the outer peripheral portion of the reinforcing plate is depressed toward the bottom plate. A depressed portion is formed, and in the welding step, the depressed portion of the reinforcing plate and the inner wall surface of the side wall are welded.

  According to said structure, the depression part of the said reinforcement board and the inner wall face of the said side wall are welded. Therefore, the weld metal (at least one of the metal constituting the reinforcing plate, the metal constituting the side wall, and the metal constituting the filler metal) melted at the time of welding is the depressed portion of the reinforcing plate and the inner wall surface of the side wall. It collects in the space surrounded by. For this reason, the weld metal melted at the time of welding does not form a welding mark that protrudes like a bump on the surface of the reinforcing plate, or does not form a welding mark on the outer wall surface of the side wall.

  Thereby, when using the structure itself which consists of the said baseplate and the said reinforcement board as said base, the fall of the beauty | look which arises by a welding trace can be suppressed. Moreover, when using as a pedestal what covered the structure which consists of the said baseplate and the said reinforcement board with the resin-made covers, it can avoid that mounting | wearing of a cover is inhibited by a welding trace.

Embodiment
An embodiment of the present invention will be described below with reference to the drawings. The display stand according to the present embodiment is for installing a liquid crystal display, but the present invention is not limited to this. That is, the present invention can be applied to a display stand for installing an arbitrary display (preferably a thin display) such as an organic EL display.

(Structure of display stand 20)
The structure of the display stand 20 according to the present embodiment will be described with reference to FIGS. 1 and 2.

  FIG. 1 is a three-side view of a display stand 20 according to the present embodiment.

  The display stand 20 is for installing the liquid crystal display 10 on a flat surface (hereinafter referred to as “installation surface”) such as a shelf board, and as shown in FIG. 1, a pedestal 21 placed on the installation surface, The support column 22 standing on the pedestal and the attachment portion 23 provided at the upper end of the support column 22 are provided. By fixing the back surface of the liquid crystal display 10 to the attachment portion 23, the connection between the liquid crystal display 10 and the display stand 20 is realized.

  The pedestal 21 is a plate-like structure whose longitudinal section is curved like a bow (see the side view in FIG. 1), and an opening is provided in the center (see the top view in FIG. 1). Since the base 21 is curved, the front edge and the rear edge of the base 21 are in line contact with the installation surface. Thereby, the stability of the base 21 is ensured. Further, since the opening is provided in the center of the base 21, the base 21 that is lightweight and excellent in aesthetics is realized even if it is large.

  Of the four sides constituting the pedestal 21, the side located on the display surface side of the liquid crystal display 10 is called a front part, and the side located on the back side of the liquid crystal display 10 is called a rear part. The lower end of the column 22 described above is attached to the center of the rear portion of the base 21. As can be seen from the side view of FIG. 1, the thickness of the front portion of the pedestal 21 is thinner than the thickness of the rear portion of the pedestal 21. This is a consideration for preventing the user who views the display stand 20 from the front from feeling the thickness of the base 21.

  The pedestal 21 is composed of a metal base plate 31 having side walls and a structure 30 produced by welding the metal reinforcing plates 32 to 34 surrounded by the side walls so as to face the bottom plate 31. It is covered with a cover made of metal. FIG. 2A is a top view showing the structure 30, and FIG. 2B is a top view showing the bottom plate 31 and the reinforcing plates 32 to 34 constituting the structure 30 individually.

  As described above, the pedestal 21 of the display stand 20 is an annular structure, and sufficient strength to support the liquid crystal display 10 is ensured only by covering the bottom plate 31 serving as the skeleton with a resin cover. Can not do it. In view of this, in the display stand 20, metal reinforcing plates 32 to 34 are welded to the bottom plate 31 to ensure sufficient strength to support the liquid crystal display 10.

(Structure of welded part)
The structure of each welding part contained in the structure 30 which comprises the base 21 is demonstrated using FIGS.

  3A is a photograph showing the appearance of the region A of the structure 30 (see FIG. 2A), and FIG. 3B is a cross-sectional view taken along the line A1-A2 of the structure 30 in the region A (FIG. 3). 2 (a)).

  As shown in FIGS. 3A and 3B, the bottom plate 31 has a side wall on the outer peripheral portion. This side wall may be formed by performing an L bending process. The reinforcing plate 33 is disposed in a space surrounded by the side wall of the bottom plate 31 so as to face the bottom plate 31, and has a recessed portion that is recessed toward the bottom plate 31 in the outer peripheral portion. This depression may be formed by drawing. In this depressed portion, the reinforcing plate 33 is welded to the inner wall surface of the side wall of the bottom plate 31. Therefore, the weld metal 41 (the metal constituting the reinforcing plate 33, the metal constituting the side wall of the bottom plate 31, and the metal constituting the filler material) melted at the time of welding in the welded portions A3 and A4 is fixed in the depressed portion. Therefore, it does not flow out to the outer wall surface of the side wall of the bottom plate 31.

  As described above, the display stand 20 can have sufficient strength to support the liquid crystal display 10 by welding the reinforcing plate 33 to the inner wall surface of the side wall of the bottom plate 31 in the depressed portion of the reinforcing plate 33. And since the welding trace is not formed in the outer wall surface of the baseplate 31, the beauty | look is maintained.

  4A is a photograph showing the appearance of the region B of the structure 30 (see FIG. 2A), and FIG. 4B is a B1-B2 cross section of the structure 30 in the region B (see FIG. 4). 2 (a)).

  As shown in FIGS. 4 (a) and 4 (b), the bottom plate 31 also has a side wall on the outer peripheral portion in a portion where the reinforcing plate 33 and the reinforcing plate 34 are adjacent, as in FIG. Similarly to FIG. 3, the reinforcing plate 33 and the reinforcing plate 34 are also disposed in a space surrounded by the side wall of the bottom plate 31 so as to face the bottom plate 31, and are depressed toward the bottom plate 31 in the outer peripheral portion. Has a depressed part. In the depressed portion, the reinforcing plate 33 and the reinforcing plate 34 are welded to the inner wall surface of the side wall of the bottom plate 31. Therefore, the weld metal 41 melted at the time of welding in the welded portions B3 and B4 is fixed at the depressed portion, and therefore does not flow out to the outer wall surface of the side wall of the bottom plate 31.

  Thus, also in the part which the reinforcement board of the structure 30 of the display stand 20 adjoins, each reinforcement board has a depression part recessed toward the bottom board 31 in an outer peripheral part, and the side wall of the bottom board 31 in this depression part It is welded to the inner wall surface. Therefore, the same effect as described above can be obtained also in the portion where the reinforcing plate is adjacent.

  5A is a photograph showing the appearance of the region C of the structure 30 (see FIG. 2A), and FIG. 5B is a cross-sectional view taken along the line C1-C2 of the structure 30 in the region C (FIG. 5). 2 (a)).

  As shown in FIGS. 5 (a) and 5 (b), also at the corners of the structure 30, the bottom plate 31 has side walls on the outer periphery, as in FIGS. 3 and 4, the reinforcing plate 34 is also disposed in a space surrounded by the side wall of the bottom plate 31 so as to face the bottom plate 31, and is depressed toward the bottom plate 31 at the outer peripheral portion. Has a depression. However, the depressed portion in FIG. 5 is different from the depressed portion in FIGS. 3 and 4 in that it is inclined toward the bottom plate 31. The depressed portion in FIG. 5 may be formed by bending the reinforcing plate 34 toward the bottom plate 31. 3 and 4, the reinforcing plate 34 is welded to the inner wall surface of the side wall of the bottom plate 31 in the depressed portion. Accordingly, the weld metal 41 melted at the time of welding in the welded portions C3 and C4 is fixed at the depressed portion, and therefore does not flow out to the outer wall surface of the side wall of the bottom plate 31.

  Thus, in the corner portion of the structure 30 of the display stand 20, the reinforcing plate 34 has a depressed portion that is inclined toward the bottom plate 31, and is welded at the depressed portion. Therefore, the same effect as described above can be obtained at the corner portion.

  6A is a photograph showing the appearance of the region D of the structure 30 (see FIG. 2A), and FIG. 6B is a cross-sectional view taken along the line D1-D2 of the structure 30 in the region D (see FIG. 6). 2 (a)).

  As shown in FIGS. 6A and 6B, also in the front portion of the structure 30, the bottom plate 31 has side walls on the outer peripheral portion as in FIGS. 3 to 5. 3 to 5, the reinforcing plate 34 is also disposed in a space surrounded by the side wall of the bottom plate 31 so as to face the bottom plate 31, and is depressed toward the bottom plate 31 at the outer peripheral portion. Has a part. However, as described above, the outer peripheral portion of the front portion of the display stand 20 is thinner from the bottom surface to the upper surface than the other portions. Therefore, the side of the outer peripheral portion of the reinforcing plate 34 is bent toward the bottom plate 31 in the depressed portion of the welded portion D2 in FIG. 6 and is different from the depressed portion in FIGS. 3 to 5, the reinforcing plate 34 is welded to the inner wall surface of the side wall of the bottom plate 31 in the depressed portion. Accordingly, the weld metal 41 melted at the time of welding in the welded portion D2 is fixed at the depressed portion, and therefore does not flow out to the outer wall surface of the side wall of the bottom plate 31. In addition, about the welding part D3, since it welds in the depression part inclined toward the baseplate 31, like welding part C1 and C2 demonstrated in FIG. 5, detailed description is abbreviate | omitted.

  Thus, at the outer peripheral portion of the front portion of the display stand 20, the reinforcing plate 34 has a depressed portion in which the side of the reinforcing plate 34 is depressed toward the bottom plate 31, and is welded at the depressed portion. Therefore, even when the side is a depression, the same effect as described above can be obtained.
